Worst teacher ever! dont take him! just copies the book and doesnt know anything when asked. Midterms are ridiculous, when the whole class does THAT bad there is SOMETHING wrong!!! but instead of compensating with the second midterm he does it again!

He's full of information but has no clue how to part with it. Definitely has favourites in the class and blatantly shows it. Explaining is a foreign word to him.

avoid at all cost!!!! TERRIBLE TERRIBLE PROF...very funny guy, im sure he's nice as hell but dude just cant teach...goes extremely fast...when you ask him a question outside of class does everything to make you look dumb..i was able to understand more reading the book on my own!!!!!

Stay away from this guy. He doesn't know anything about the subject and he has weird marking scheme.

DONT TAKE THIS PROF FOR ANYTHING! its a lot of work and its useless, he cant explain anything properly and u are bound to fail unless u get another teacher.. good luck if ur with him, u'll need it!

I've never taken a physics class before this one, and it was not a good idea. It's clear that you must have some background before entering this course otherwise, it is impossible to pass. Keep up with the homeworks because it feels like the finals and midterms are only out to trick you.

He should not be teaching. He knows physics(or at least gives the appearance), so maybe he should be working. But definitely avoid class. Id rather wait another semester than take it and be left with learning all on my own. His english is fluent, but he has no ability to communicate. And hes power hungry too.

He does not know how to teach.You have to mark your own assignments LOL.Once he said he need to talk to me after class. I go to him and he says why did you give yourself such a high mark,you should not do it else I will give you an F. I told him stop being lazy, marking is not my job. Stay away fom this guy, he just makes you hate science.

I think he is the worst professor ever. Believe me guys, he is very bad. don't take any course with him ever.

Worst professor at concordia, taking 205 with him is worst decision i have ever made, does not explain anything, can understand, gives 20 problems on midterms and no one finishes?? Avoid this professor as much as possible, especially for a difficult course like physics 205.

Definitely the worst professor I have ever had. He makes me despise my program and university in general. He does not give part marks so if your final answer is wrong, you get 0. The course is confusing as it is and going to the lecture makes you more lost. I strongly recommend a different professor!!!!

Potential students: Skim through the comments regarding this teacher.You'll notice that they are almost all negative.I decided to risk it and join his class despite these comments, assuming they were exaggerated. Do yourself a favor and heed the warnings.You will suffer.

The worst teacher I have ever had.If,you have him, take my advice and drop the course immediatly.Otherwise,goodluck.

the worst teacher ever.Avoid him.Very hard assignment and exams and above all, he doesn't explain well.

Very unclear and error prone. Exams are too long, yet he is unforgiving when correcting them.

this is the worst professor ever. Don't ever try him in any course. Otherwise, goodluck.

Terrible professor, lecture are confusing the midterm and finals are really hard and the average is a around 40 percent, avoid as much as possible!!

Worst prof ever. Very strong accent and completely incapable of explaining clearly. Is lazy, gets upset when you ask questions, can't solve problems unless he has the solution in front of him and is a ridiculously hard marker (no part marks on 10 pt questions). Avoid if you can. If not, good luck!

Terrible teacher. Expect to know Physics before this class, otherwise, you probably will fail. He doesn't assume you have other classes. Unless you're pretty much proficient at Physics, you will have a hard time. Midterm was extremely difficult, more than 85% of the class failed, and the teacher still thinks his midterm was fair. Avoid at all cost.

I cant believe how some comments here are really deceiving. This guy is the worst one ever and believe me you'll have terrible time with him.... For me I prefer to drop the course other than dealing with this irresponsible person.

this is the worst prof. u can ever see in ur hole life!! if ur gonna take a course with him 90% ull fail..

why ?!?!?!!??!!! i did nothing to deserve this ! :( well here how it goes.....i went in happy . optimistic :D then when the midterms came i was excited ! ready for the exam ! i thought i was gonna ace it ! until i saw the type of questions..

Even tho I aced this class as I am proficient in the subject, this was the worse learning experience ever! It is a great mystery as to how or why this person is where he is. Not only can he not speak english but his explanations were incoherent. He seems angry when asked questions. Avoid this prof at all costs, unless you are a masochist

Teaching style is terrible because all he does is throw formulas on the board for you, solve for certain variables, and expect you to understand everything. This course is very doable without too much work but you have to stay caught up with the curriculum, if you don't study, you don't pass-it's simple. His exams are straight from the assignments.

Beware of dog and in this case it is a mean, violent and ugly pitbull. I think this prof has an anger management issue. I made 1 request and he bit my head off for no reason. No ounce of mercy from this guy, no matter how bad or well you are doing in his class. He is a control freak, he is mean and ugly and his class reflects these qualities

worst teacher ever!! I have no idea how Im going to pass this couse... He doesnt give power points online and reads a bunch od useless paragraphs from the texbook in class, avoid this teacher by all means!!!

Woe to all who do not heed the warnings here. Avoid this prof a million times over. No structure in class, and he seems to be in a warped garden of incoherence. He will make you rue the day you have taken his class. He will butcher any interest in science and fail you. Woe to those who decide to take this prof. You have been warned.

This guy is terrible! AVOID AVOID! If you ignore these comments and do take him, be prepared to do webassign assignments with absolutely no solutions and to do extremely useless chapter reviews. His notes are terrible and he cant explain anything clearly. 18 out of 103 passed his midterm, but he'll tell you it was fair. Should not be teaching!!!

Listen to these warnings. They are all true. Stay away from this prof. A real loser as a teacher...so much for quality education. This guy has no qualities as a teacher, only just full of himself and power mad. Puts education and learning to shame. He should be shipped out cause there seems to be no shaping up.

OMG! Is this guy punishment for my sinning soul?No empathy on my plight, nor does he have any idea on how to be a teacher or how to communicate tough concepts. Lectures are confusing and thrown together. I think I am going to fail this class, and now my GPA is going to be all messed up thanks to him

Worst teacher to date. Isn't the point of going to class to get it there, and not have to book private meetings in a crummy little office with a dirty little man, doing God knows what behind a closed door? If you like getting tortured by a small man who thinks he is God's gift to students, then by all means do so.

I am so glad the semester is over so I do not have to listen to this guy killing the English language. The only thing this guy gave me was an anxiety attack over passing this blasted class. Good riddance to you and your awful teaching methods, may I never have to see, hear or think about you again. Oh blessed joy!!

He is a very smart teacher and knows his stuff very well. however he does'nt teach well at all. his pop quizes, midterms and exams are very hard. he doesnt like answering questions in class. i suggest you never take a class with him.

THE WORST PROFESSOR EVER. if you can avoid it, get anyone other than him. he has lost my assignments, just goes from the book and dosent teach you anything

Horrible teacher, he's smart but no idea how to help you. He's always mad, take any other teacher.

Well... First of all, he hides mathematical traps in his exams,he does not explain his assignments, totally unorganised, changes his mind without notice, overcomplicates already somewhat complicated subjects (seriously, he's going to do triple integrals and class-long proof when he could just explain it in less than 5mins).Just, don't take him.

horrible

Completely unorganized, impatient, may as well learn onlin and on ur own. Has no ability to teach or speak well. You're paying for the credits u get for passing the class, but if u want to actually learn and be in a productive environment, well run away. In all my years this is the WORST professor, hands down, regardless of the course.

This is my second class with him and I probably forgot what knowledge I had about physics. bloody awful

One of the worst physics profs that i have had. He gets on the board, starts one example the does a side note unrelated to the example, starts a secound example and if you are at all lucky he may finish one of them. The slides he uses are also not the greatest. He will not answer your questions, he will make many mistakes. AVOID!!

He is the worst teacher i've ever met. He's not only terrible, he's also out to get you. 1/3 of class fails. The smart ones drop it in the first week. Avoid at all costs. And i'm not even bitter, I did well in this class.

Very arrogant prof, goes too quickly through the material and does not like to give explanations or any help for that matter. Also hes a very tough grader. Avoid as much as possible

he is the worst teacher I ever got. I don't learn anything from his class, his teaching skills are literally absent. the book is not great either. The awkward moment when youtube teach better than your teacher, it's sad.

On his tests he'll take points off of a multiple choice question if you don't show complete work. I've never heard of anyone doing that before.

AVOID AT ALL COSTS! I love Physics, but this professor ruined the mechanics course for me.

does not explain and you will get the hardest assignments and tests ever

Disliked this class and his teaching method very much. Knows the material but doesn't seem so enthused to be teaching. Highly recommend avoiding this class.

avoid his class at any cost

Lecture is useless. Very complicated teacher. A tutor is a lot better than him to explain the concepts. Just do all the problems from the book and you will pass this course. Midterm average grade was less than 50%. I do not recommend this teacher if you are willing to pass this course with an A+ or if you took other hard courses with this course.

Worst professor I've ever had. I'm a very diligent student and this is the first time I couldn't bear sitting through lectures because he honestly doesn't form cohesive sentences nor explain conceptsapplicationsanything. He doesn't seem to care at all about the material, gets irritated with questions, and is just awful. Don't do it!

He is specialized in making this complicated , lectures are so boring but you better attend them because he might give you pop quizzes.

Lectures are not relevant to homework material so learning on your own is a must. Questions were discouraged after a couple classes due to his inability see people struggle with material that he knows well. Pop quizzes are a thing so despite the useless lectures, you should attend class. I would suggest a tutor if you cannot get into another class.

First off this class is very abstract,and this prof does nothing to help you understand the concepts any better. He's useless and will make you feel stupid when you ask questions. All i can say is just study hard, invest in chegg account so you have answers to problems and also it will help big time with assignments, watch youtube videos also.

Very boring, long lectures and usually during the evenings. Very tough assignments and practice questions. Hard, long final, however, some questions are from class examples. Gives pop quizzes at the end of class, make sure to always stay to the end.

not a pleasant experience at all. Don't aim for anything above C+ in his class if you are an average to smart student; and so in general avoid him if you want to pass

physics department in concordia is bad but this one over here surpassed all limits. avoid him. he doesnt help, doesnt understand situations, doesnt give tips and mostly he doesnt care about his students not a single bit

The class average for the winter 2016 was 51%!! That is horrible, most of the students including me were angry and annoyed by his exam, because he really tried hard to fail us. He goes very in depth about explaining each formula and because of that everyone will leave the class confused. You probably need to spend on tutorial Classes to pass :(

Worse Teacher I've ever had. His teaching style is to show you how well HE understands the material. Does not allow you to bring your own formula sheet to exams like other PHYS 204 sections. His lectures are way too theoretical and not practical, most people seem to be confused by his explanations. Oh yeah did I mention pop quizzes? AVOID!

Avoid at all cost. He will teach you Italian and ask Spanish. And in his defense they are both latin languages. Seriously avoid if you like passing, Physics 204 is surprisingly an interesting topic when its not him teaching. Moreover goodluck to whoever takes him in the future.

I have since a young age been passionate about physics but when i had this guy oh boy doesnt care about students and doesnt take the time to explain and make things clear. He just writes 1 after the other like a robot. This is not what a teacher is. I feel depressed and im a studious person who loves to learn. AVOID HIM.

He's terrible, he thinks because he knows the material we will right away understand. Doesn't explain anything, just writes. Study the whole book and exercises and you'll do good everything is explained in it!!

Absolute horror! AVOID at all costs. He takes being completely useless at teaching to a whole new level. Instead of teaching physics concepts, he spends all class time doing mathematical proofs! Lectures mandatory (quizzes). Do not ask him questions, he hates it. DO NOT BELIEVE HIS SAMPLE EXAMS FROM 10 YEARS AGO! His actual exams are NOTHING alike.

He has absolutely no business teaching. Easily the worst I've had. He's so unfocused in class, jumping from one thing to another, makes mistakes all the time, writes a bunch of equations and doesn't explain them, plus he sometimes refuses to take questions! I finally gave up going to his lectures; I studied from the book and went to the tutorials.

terrible prof i suggest not taking the course if he is the only one teaching.

If you love learning by theorem proofs then this is your professor. But if you're the other 99% that find proofs useless and would rather be taught by applications of equations and examples, then avoid Abinader. All he does is proofs, showing how one equation is derived from or equal to another. Rarely does he do examples so the hw is challenging

One of the most banal, ugly and funky smelling teacher. How he got this position is a mystery to end all mysteries. Talks and says nothing, cannot teach or relay complex concepts. Should be on the list for teacher removal, he cannot teach, and torments you with long and useless talk about how his ass defies the laws of physics. Get rid of him!

Doesn't care about students and expects you to know everything while teaching solely theoretical problems. You need to study hard and on your own. I'm sorry if you have to take his class..I deeply regret choosing this professor for a subject I already struggle with.

You don't learn anything in lectures and says there isn't enough time for questions. Problem is, during the time he talks, it's useless theory that won't help on the exam. I regret taking this class and I hope he gets removed someday. Use Khan Academy for basics but for the test he integrates numerous topics into one question. Way too hard.

He is simply not good at teaching the material in a clear and easy to understand way. He likes to spend the almost the whole lecture writing his notes on the blackboard with his back to the students. During this time he will not take questions from students. His midterm was not very hard but not easy. Can't say about final. I dropped course halfway

His explanations are okay but the material in the exams are nothing like it. The midterm was ridiculous ( 15 questions in less than one hour). The average is usually crazy low and usually everyone gets a boost to even it out. He also makes you buy the Ebook (for 150 ish $) so dont waste money on the hardcopy of the book.

Has very unrealistic expectations of the students. He has no idea how to run the online course, somehow he thinks that we are the only course he has. The material is not taught properly. The midterm was a joke because we didn't have enough time to finish the questions since we had an hour and 10 questions and one hour. AVOID AT ALL COSTS.

If you want to save your life Take this class at cegep

He would not respond on time. He would change the deadlines of the assignment, I was not able to do one of them because he put the deadline on April 30th, 2019. Thinking you have until that time, he changes it a week earlier, and then tells you that it is your fault for not doing it on time. Please consider taking another professeur.

Probably the worst teacher I've ever had. Don't bother sending him emails because he'll never answer back. Try your best to avoid him at all costs.

Run before its too late

RUN RUN RUN RUN RUN RUN RUNNN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

At first you will be deceived by his smiles and theoretical explanation, but then you will realize why his rate is disastrous. He does not respond to emails. He keeps changing assignments deadlines. He just explains theories. He taught us two chapters literally before the exam day. Simply avoid.

Just avoid this prof at all costs

If you love yourself, don't take this professor, even if your life depended on it.

whatever happens, don't take physics with him, even if you have to, or risk losing your interest about physics for ever and ever. you have my word.

If it were possible to give 0 out of 5 his rating would be 0.001. Avoid at all costs. Take another course and try next semester if he's the only one teaching

Doesn't answer emails, condescending when asked questions, and only teaches theory in class without examples. His handwriting and notes on the board are all over the place. Outline said 4-6 pop quizzes, but he decided three weeks in that he would give one every week. At least he was true to his word about that. Laziest prof I've ever seen.

not the best option lectures and final are very different!

There's a reason his rating is dreadfully low on this site and from past students advice, just avoid this guy at all costs

I had a very bad grade on the midterm, reason why is: the exam time was 75 minutes with 11 questions requiring clear calculation which requires an average of 7 mn per question, the 5 first question require 10 mn of thinking just to understand and start resolving problems. this class was outrageous. other classes/online had the same exam in 135 mn

Absolute trash teacher. He is the worst. Terrible explanations, condescending and rude when you ask questions, does not help students outside of class, exams are extremely difficult. It is not fair to the students of Concordia to keep him employed as a teacher!

If you have an ounce of respect for yourself, don't take his class!! He's a monster and inhumane, he has something against his students cause you can sense how badly he wants everyone to fail!! a classic sociopath.

Never again!

Took his Phys205 online course, he's not the lecturer so the course is fine. He curved everyone's grade DOWN in order to fail more people. Here's a section of his email. "I had to curve them down. The curving down was made by multiplying the grades by the factor of 0.82 that would generate an average of 61%"

Abinader is by far the worst professor at Concordia. Not only is he rude and curt with his students, he doesnt care about their success or studies at all. For the PHYS 205 EC course over the summer, over 60 students received an F because the proctorio software didnt register their exams, and Abinader juat said that he couldnt do anything.

Ridiculous to say that he is a "professor". After midterm half of the class were gone. Just don't take it. His handwriting is awful like his teaching. Just don't waste time on this man and wait until someone better teaches.

Never answered a single email on time from me, and sometimes he doesn't answer them at all.

The absolute worst professor in Concordia. Not accommodating for students. Honestly, it says something when a professor takes pride in the number of people who fail his class. Would be worth it to change the entire academic year schedule to avoid having him as your teacher.

In two degrees this is absolutely the worst professor I've ever had. Higher workload than other sections of same course, outline was disorganized and didn't match the material making it hard to plan your weeks, takes weeks to answer emails, calculated midterm grades wrong accidentally failing the entire class and didn't even notice.

Did not love the guy, partially because I never saw him. I took the course online, all recorded lectures were done by a different prof, however assignments and quizzes were taken from an online platform, midterm and major were incredibly difficult and did not line up entirely with recorded lecture material

what i learned from this course is that i can be my own teacher bc this prof doesn't teach anything.

Passing his class is equivalent to finishing a game in LEGENDARY MODE. Basic physics courses already have a 50% FAILURE RATE on EASY MODE. A letter grade of C is equivalent to an A+ in the same class but with a different professor.

Never responds to his email, he gave me a 67 % on the midterm even though I was sure I aced it, didn't even give back the midterm, and refused that me look over it. he doesn't respond to questions, and gives a sh*t load of work to do that is frankly impossible to do unless you use external resources.

We are all a bunch of masochists and he is the sadist whipping us. We like pain and this prof provides it in abundance. Fine, Concordia is not the highest rated university but the bar is so low and teachers like this guy get into the system and wreak havoc on poor unsuspecting students who don't know better than to take him. Good luck if you do.

If you have Abi Nader ONLINE (recorded lessons, not his own) in your 1st year, he will ensure that you FAIL the course. His midterm and final exams are NOT aligned with the textbook material and the difficulty level is at 10. Concordia University uses him to fail students, so that they can make additional money by having them repeat PHYS204.

this guy is literally the epitome of "that one teacher thats gonna make you hate physics". your best friends will be organic chemistry tutor, previous finals and assignments if you want any chance of passing. does not care about the success of his students and even lied about a certain chapter being included in the final. please do not take him

Never responds to emails, is never accessible (for me), study materials and exams are not aligned, and weekly assignment (takes overall 1.5 hours) and weekly quizzes. In a nutshell, If you want to fight the demon take his classes and I will guarantee you that you're gonna fail. The worst professor doesn't care about anything as if he's high 24/7.

He wasn't helpful throughout the course. I was confused the whole semester even though I read my textbook. H wasn't able to explain what stuednts were asking. If you can avoid him, DO IT.

The dude is awful. He didn't even teach this term. He just put videos up and sent us on his mary way. Want to pass his class? Do all the webassigns and the extra problems for each chapter

I got a good grade for only 2 reasons: my own individual hard work & the very big curve he made because most of the class was failing This guy is the most arrogant, disrespectful, disorganized and rude professor I ever dealt with I have taken my other physics courses with Nima and he was absolutely amazing So if you can drop Abinader dont hesitate

THE ABINATOR PASSED CUZ CURVE THO SHESSSSSSH BROS A TIER ONE OPP TO MY MENTAL HEALTH

He forced us to watch recorded zoom lectures and never taught anything.

he makes you to hate physics! WONT take class with him again and ignore positive comments such as easy or fair exams

In my 16 years of being a student this is easily the worst professor I have seen. He assigns homework which takes hours to complete worth 1 percent per assignment. His tests are difficult and impossible to finish in allotted time. You will struggle in all other classes because of him. It is a shame that the university allows this. Stay away.

The worst teacher you will ever find in your life. Tests are impossible to do. He tries to find the hardest questions ever, and impossible to do in in the given time. NEVER take him.

Turn around and run for your life. This guy will give you only regret, frustration and a run for your mental health. This teacher is not for the weak. Has absolutely no empathy nor foresight in how complicated a student's life could be. He will chew you up and spit you out.

The worst prof of all time!!! hard exams hard grader and has no respect for the students.

People who do good in phys 205 with him is because they know where he gets his exam questions from. He has a testbank...You find it you're good. If you don't, get ready to fail because no matter how smart you are you will struggle with this class. This is coming from someone who's taken phys 245 (a way harder class than this) and did exceptional

He is a terrible person, no respect for the students, their education nor their time. he does not respond to emails and does not help at all. It is a big shame for Concordia university to keep such teacher and not do anything about this big issue in their physics department. DO NOT TAKE COURSES WITH HIM NO MATTER WHAT SITUATION YOU ARE IN.

At first, he wasn't qualified to teach this type of course at the university at all! Secondly, his awful accent made all of us uncomfortable in class! Last thing but not least he always tries to force us to do extra homework even the night before the exam! With all due respect please don't take this course with him.

Run for your life. Gonna ruin your mental health. If theres no other professor teaching the course you wanna take at that time just wait for next semester and fill something else. For your sake and the sake of paying so much dont ruin your gpa i am already stuck in this hell pray for me

Do not sign up to his course if you want a professor with proper English and basic ability to teach

you wont be able to understand anything from him he barely speaks english, and when he talks he will be talking about Shakespeare or how good he is at physics.

The most complicated lectures, inconscient symbol use, and over incomphrendable material. Good luck :(

they give phds to anyone these days, i doubt he's taken 1 education class

He may be the worst teacher I have ever had in my years of education. Get ready to have mental breakdowns and not have enough time to do anything in the world. The material is fairly comprehensible, but oh man, he CANNOT TEACH FOR THE LIFE OF HIM. He gets his notes copy and pasted from the textbook, no additional info is taught. Avoid at all costs

My experience with this professor is awful. I STRONGLY urge Concordia to get rid of him as he is a nuisance and does not help students in any way shape or form. He should not be certified to teach and has been consistently giving poor quality lectures as well as significantly overworking his students. He does NOT care if you succeed.

Help. Horrible midterm impossible to do in the amount of time given. His lectures are too heavy and the assignments take forever to do. Do not take this teacher :)

He's horrible. Makes no sense during lectures and talks to himself the whole time. I would definitely not recommend him if you haven't taken a physics before. His midterm was so hard and almost everyone failed. Try and take this online just so you doing have him. He is no help and doesn't speak very clearly or well.

Avoid at all costs, even if your only other choice is a late-night lecture. He gives super long assignments every week that take forever to finish. Lectures are useless and I had to learn the whole course on my own with the textbook so this class ended up consuming most of my time which led to me struggling in my other classes as well.

I have never had a teacher decrease my will to live so much. My other profs are not the greatest, but at least I don't dread every class. Midterm was impossible, over half the class failed. He also doesn't teach anything, so be prepared to pay mandatory $90 for the textbook, but hey!!!! At least you WILL use it. I'm so mad. Save yourself.

AVOID! But if you can't, teach yourself. I only did well by taking two full days a week for this course. I did not go to a single lecture after the first month. He is unprofessional, impossible to understand, and exams are long. (Found myself crying during the midterm cause he was yelling at us.) You CAN do well, but it will be in spite of him.

One of the worst professors. Doesn't know how to teach at all, talks about one random topic the whole class and skips slides. His powerpoints make no sense and are outdated. So many assignments and quizzes every week and hard exams. Even if you ask him questions he doesn't help at all and doesn't care. Don't take him, you will regret it.

Don't know ANYONE who has passed this course. People say he curves but it didn't look like it this semester. Worst professor ever, if you even want a chance to pass, don't take him. He needs to get fired.

AbiNader is the type of teacher that simply cannot teach. He has a good grasp on the subject matter but that means nothing since he cannot run a classroom. Prepare to be bored while he rambles about drawing diagrams for the 500th time. The assignments are long and he refuses to give extensions.

This class filled me with so much rage. He overcomplicated all of the content, and taught proofs and examples that were far beyond the scope of the course. He would go through easy examples and then put difficult questions on the exams. The weekly (SOMETIMES TWICE WEEKLY) Webassigns were awful. I felt like I was in a fever dream every Wed night.

He can barely teach but if you put in the work its fine. I spent a few hours before each lecture teaching myself the material, and ONLY THEN I could follow his lectures. The worst part is his demeanor and the environment during class...was rude to the TAs in front of everyone... clearly annoyed by questions. He knows physics. He is just unpleasant.

This teacher is so hard.

My experience with him is that i find that he doesn't care, and unreachable. Send email, ghost, send message ghost, and then during exams even if the whole classroom will have an issue= GHOST. And i'm sure he knows the frequent issues students deal with during online examinations, and he won't let you know in advance or include useful instructions.

Yelled at us to hurry up during the midterm. Doesn't let you take photos of the notes even though his writing is eligible and he forgets to switch over to the projector half the time. Long assignments. Heavy accent. Goes into proofs instead of teaching us the questions we're given. Awful at answering questions. The list goes on...

Had him in Econ. Assigned to us 3 weeks into the semester so it was too late to drop. He doesn't respond to the discussion forum, ever. One practice exam to prep for finals, challenging yet doable. Final exam he created, nightmare. Took the most challenging version of problems, that we never covered and made them the long answer section. The worst

Faculty gives this professor a LOT of power, and he knows it. (i promise you it's not an exageration), he doesn't grade, TA's do and it can be unfair and he will allow it, he will NOT help even if issues happen to the whole class, and yes final is difficult and yes the online class doesn't prepare you for it. some get curved some don't,

I took his PHYS 204 online class for my first term. At first it seemed easy everything was going well. The Midterm wasn't tough got a very good grade on it. Everything was well until I reached the final. Nothing and I mean nothing could have prepared me for what was on that paper. 129 students failed his class. 129 out 150. Let that sink in.

Takes 2 months to reply to emails, even then, you might not get a response, his assignments are long and done in a way where you spend more time just getting them done than actually learning. horrible teacher

Save your money and transcript. Don't ever take this prof 70% of the class failed.

Difficult teacher Got a bad grade in midterms cuz the exam was proctored and it was impossible to upload pictures of my worksheet and also he refused to acknowledge that issue despite being mentioned multiple times by students in the general discussion. Don't even bother emailing him, he will ghost you

He used other professors' lectures; he never answered emails, nor did he provide office hours. He never corrected anything, everything was automatically corrected. His homework and the lectures used were not enough to prepare anyone for the final exam. In conclusion, he was paid this semester only to correct the final exam, and he took 20 days.

genuinely the worst I read all the reviews thinking he couldn't be so bad, he was terrible . I retook the class with Shin and got a B+ . Save yourself i'm telling you now .

Just avoid him. He is not a good teacher, even if you have him online; his assignments are too long and don't teach you anything.

He was not a professor. Taught nothing. Midterm was a mess, with students chasing after him & TAs through emails to get grades modified after some complications. The assignments are LONG. I learned more in a summer intensive at a college than a whole semester in his class. This class was so demanding it took time from other classes. Do NOT rec.

Did the midterm yesterday, we had 1H15min for it. Very hard because there is no time to think, you have to know it all when you write it, very difficult long questions. I will not judge him as a person but as a professor, he did not teach well and did not prepare us well. Physics 204 should not be this hard, the time for the exams is too low.

drop him!!

He doesn't speak well and is bad ay explaining

Never again taking the course with him.
