Absolutely deplorable. first exam average was 40%. second exam average was 51%. he DOES NOT teach, doesn't post notes on BB, doesn't respond to email, doesn't care about any of the students! worst professor ever.

Worst professor I've had so far. His accent is so thick you can't understand him, he refuses to post his lecture notes online, and he goes through lecture so quick you can't understand him. I had to go to other instructors for lecture notes and turn to online resources to understand the material better. DO NOT TAKE THIS PROFESSOR.

EXPECT TO TEACH YOURSELF! I relied on PPTs that he posted so I could study before exams, until he stopped posting. I don't think tests would've been hard if he had given similar practice problems during lecture. Not long useless examples that werent on tests. Post-final, everyone is on their toes waiting for a miracle to happen to their final grade

Dr. Fayissa is a fairly nice, genuine man. But he should not be in the field of teaching. His heavy accent and monotone voice makes it very hard to understand what he's saying. I didn't learn a single thing from his lectures. He takes his slides straight from the textbook. PLEASE if you love yourself, DO NOT take his class!!

WORST PROFESSOR EVER. I'm not sure why but he was the only professor teaching CHEM 212 this semester. I had to take him to graduate on time. You will not learn a thing from his lecture. It is impossible to understand him due to his heavy accents. His lectures are just reading off the powerpoint. Prepare to learn by yourself from reading the book.

He has is not helpful outside of class. His lectures aren't clear, and he doesn't post notes or any supplemental help.

Fayissa is one of the worst professors I've ever had in my academic career. His accent makes everything hard to understand, the material is extremely difficult, and you feel like you are on your own with everything. I will never take Fayissa again

Professor Fayissa is one of the worst professors I've ever had so far. The class average on the 2nd exam was a 30%. He is a really really nice guy but his voice and accent are horrible. Be ready to teach yourself if you want to pass.

can't understand what he is saying

Does not post powerpoints online, and he does not explain well.

One of the worst if not the worst professor I have ever had. I could never understand what he was saying during lecture because of his accent and lack of annunciation. His tests were really hard. Does not post powerpoints online and moves pretty fast through the slides. Class average was always around 50% or less on exams. Do not recommend.

Don't take him. Lectures are awful.

Not a good professor. His lectures are not clear at all, so you will wonder what is he explaining. You will also notice that so many students are skipping classes because lectures are not helpful at all and they couldn't help themselves at all.

Horrible. This professor has very heavy accent, so I had to sit at the front and pay a strong attention to understand him. You will basically have to read the textbook and take your own notes to do well. There were only 20 students coming to class, so the huge lecture room seemed almost empty. The only positive thing about him was his personality.

He's the worst professor ever. He does not post notes on blackboard and he's terribly bad at teaching. He just reads off the power point and confuses us by going beyond necessary details. I did not learn a single thing in his class. Exams are also brutal because they are nothing like homework. Self learning was extremely painful.

Professor Fayissa is a wonderful person. He is definitely one of the best people I've ever met, but he is absolutely the worst professor I've ever had. He basically tries to help students to pass, but he isn't very helpful. His lectures aren't clear and he does not fully post notes on blackboard as only few students come to class. Exams are tough.

Dr. Fayissa is another level of bad. He is not clear in lecturing and if you go to class, you will just sit there with absolute confusion. I did not learn anything in his class. Yes, he does not fully post notes on blackboard as most students skip classes. You must read. He is also a very tough grader as he rarely gives partial credit on exams.

Dr. Fayissa is not a good professor. I learned nothing from his lectures. I ended up just not going to his lectures and teaching myself all of the material. If you can avoid taking this professor, I would advise, but if not, then prepare to learn some of the material on your own.

HORRIBLE, just as bad as Oerter (A Physics professor). Half the class fails the midterms and the homework and quizzes don't accurately reflect the exam problems.

Horrible professor. Tests are nothing like what you'll learn in class and homework. Lecture notes are not fully posted. There is a curve in this class, but even then, tests are really hard. You need to teach yourself everything with the book and study many hours reviewing and practicing problems every week to get a maximum grade on each tests.

BARELY PASSED! Pop Quizes!!! He is nice but he is one of those profs where things go in one ear and out of the other. He doesn't know how to put things in simple terms. Chem isn't simple but, he will go all over the place to say 2+24. If you have to take him, read the book and understand homework (he just copies the problems/may change the #s).

Awesome man, but awful professor. He is a very intelligent man with doctoral degree and it shows, but he cannot teach for his life. Tests are extremely difficult and you have to spend 10 hours reading all chapters to learn all the materials and keep practicing homework questions to get a good grade on each test. Very stressful class though.

The class was one of the tough classes. This professor does really love students and tries his best to be helpful, but there are limits for him. His accent is really hard to hear, so sometimes I can understand him and sometimes not. Most people skip classes which has made him stop posting all notes. A really nice person, but a horrible teacher.

This professor sucks! He does not know how to teach. No notes posted. I had to read all chapters and take intensive notes (Dying) to fully understand the contents. He grades on a curve, but he is a very tough grader and will takes of tons of points for small mistakes. Do not take him unless you want to teach yourself all the materials.

I don't like to say this, but Dr. Fayissa is the worst professor I've ever had so far. I couldn't understand him at all due to his heavy accent. The class is so boring that only about 15-20 people go to class. It's really that bad. If you must take him, then get ready to teach yourself. His tests were pretty difficult as well.

Tough

Really good person to ask for help, but a awful lecturer. Lectures are dry and boring and he doesn't explain well enough for you to prepare for tests in addition to the fact that doesn't post notes on blackboard. The best person, but the worst professor.

if you don't show up to class, you're done. worst teacher in general his lectures are so bad but you might as well go. it was easy bc i took AP chem but if you didn't then you need to work. i got a B in his class when i should of had an A. he doesn't curve and if he did, it barely does anything even everyone did so bad. averages on tests were 50-70

Dr. Fayissa is very challenging. He moves really fast through slides and exams are very difficult. You'll probably need to spend more than 10+ per week on reading chapters and working on practice problems. Class is so boring and you might feel like you don't want to show up.

Awful teacher. He is very hard to understand and flies through power points then quizzes you right after. Class is incredibly boring but attendance is mandatory bc of quizzes. Study guides for tests are unhelpful and if you have miss a test for any reason he doesnt let you make it up. Often has trouble explaining things. Worst prof Ive ever had

Learning objectives are unclear. When asked for additional practice for exam prep he denied the request. He is terribly difficult to understand during lecture and often misunderstands in class questions. GPA killer. Mason really needs to get their chem department aligned if you can still switch your major DO IT. This class is not worth it.

3.8 GPA trashed after taking his class. Tell me how you can attend every class, get A's in physics, and A's in gen chem but wind up with a C in his class? The course was disorganized and the homework was not there to help you understand the course. It was busy work. The textbook does little to supplement. Good luck to all that must endure this.

This professor assigns reading and problems homework online but they're not available right away so if you want to get ahead, you can't. Coming to his lecture is only useful for the iClicker quizes that record attendance and quiz grades, but reads directly off his slides that are copied from sections of the book. Doesn't answer questions in class.

There are downsides with this professor, he always reads off the powerpoints, he grades students differently. The average on the exams are 45%-55% max, It's unfortunate how he curves the exams with his unfair grading system,I expected more from this professor. There are no extra credit opportunities, and his teaching method is so confusing.

He teaches you nothing and expects you to pass the ACS exam. Don't reccomend him at all.

One of the worst professors at Mason. Lectures were a waste of time and he never gives a straight answer. The exams are quiet difficult and he grades so harsh. Please save your tuition money and don't take his course. He is never leinent with time frames for exams and quizzes during pandemic. He should not be teaching this upper level course at all

Do not take his class. When I read the textbook most of the time I get confused with the concepts and I go to look over his lecture videos he makes, and I just end up confusing myself even more. You know I thought since I am in college the professors will all be good and know how to do their jobs, but I guess I was wrong. He doesn't teach well.

I hate to rip apart profs but man this guy is something else. This course itself was extremely difficult but he made it impossible to understand. The lectures were confusing and unclear, the exams were very hard and he does not have a clear structure for this class. He doesnt answer emails!! This was the worst experience ive ever had. please avoid.

The absolute worst professor. Doesn't communicate properly regarding times and due dates for exams and quizzes and is terrible at response by email. Ashamed to have waste money on a course where I had to teach myself the entire time with no help by this professor. Cannot express enough how horrid it was taking this course with him during a pandemic

Was awful. Did not curve, despite curving for previous years. Took advantage of going online, never uploaded practice, and homework was just textbook. Lectures were just him reading off the PowerPoint. Put zero effort into online school. Scheduled tests at the most inconvenient time, despite being asynchronous.

Very disorganized professor. Im ashamed to have spent 2k on a course where I had to teach myself the entire time. Going to lectures was a waste of time as I couldn't understand anything he's saying. He admits he goes super fast yet doesn't care. Schedules hw/quizzes/exams at the most inconvenient time. He's also terrible at responding to emails.

Horrible professor.

Had him over the summer and all I can say it was probably one of the wort experiences I had ever had at this university. Exams were very difficult, the workload was ridiculously heavy, attendance is required even though he ever mentioned it. He would announce quizzes the day before. Can ONLY use scientific or any dumb calculator instead of graphing

His whole class is lecturing. He will not go into detail on how to perform a problem, he always says "you can figure it out on your own time". You have go to class and participate because it's part of the grade. The grade on blackboard is incorrect because it is not weighted, so do not believe what it says. Be prepared to teach yourself everything.

I regret taking him for Chem 212 over summer. Besides his thick accent, his teaching style isn't the best. He doesn't go into depth when explaining problems. He rushes through slides because he assumes we will understand even though we don't. Does things at his own convenience. Doesn't care about us. Not sure why he's making chem harder than it is.

I don't understand why he is still teaching at this University. Many students are doing poor in his classes, and it's purposely made difficult for no reason. It's GENERAL chemistry. This class feels like you have to have a doctorate degree in order to understand the material and perform really well on exams.

He is not accessible outside of class. He knows his content, but is unable to teach it. Class average at each midterm was a failing grade. Called class lazy and TA did too. Rest of chemistry department was just about as helpful. Do not take chemistry unless required by your major

I don't know what's with the Chemistry department being particularly horrible. This professor is nice, which I appreciate; however, is not a great professor at all. He does not go out of his way to help students, expects us to figure things out, and makes the topics harder than it is. Those aren't the qualities of a great professor.

Literally a horrible professor -did not learn effectively from him.

My first semester was brought down (in more ways than one) by this class. His teaching was not helpful at all, he just read off of every slide and only one thing other than that the entire time (he showed us a visual/ball model, etc.) and it was the last week of lecture. The tests are difficult but all multiple choice and not many questions.

His class was quite stressful for a general chemistry 2 class. First, his accent is hard to understand. I can only understand like two words. Second, the tests are very hard and confusing and I get a C average. Third, the final is hard and it dropped my letter grade.

Mosissa has a very heavy accent making his lecture very hard to sit through and understand the concepts he goes over.

Literally a terrible professor, I don't know why he is still teaching lmao

I COULD NOT UNDERSTAND THE MAN and he looked so confident in his lecture, but I had to sit there and form the words in my head. But he was already on the next topic by then. Switched out as soon as the first class ended.

No bc I dropped his class after the second week

I want to cry

I came into this class with zero background information in Chemistry. Dr. Fayissa expects you to already know the material, breezes through things like they're recap, refuses to walk through problems in class because "it's doing the work for you", lots of homework and failing averages in exams. Do the homework, it will save your grade (Auto 100's).

Besides the fact that he is very hard to understand due to his heavy accent, he doesn't care about your performance in his class. You can ask as many questions as you want, don't expect an actual clarification. I hardly showed up to class because I didn't gain anything from it anyway. Taught myself from the book and did okay.

Dr. Fayissa's accent is hard to understand and he doesn't completely finish his thoughts. Read the textbook before class/learn the concepts before class, do the homework, and do the clicker quizzes to do well in this class. Sometimes his exams didn't match what we learned in class, but if you study for your ACS final you can really do well on it.

He is a nice man and is willing to help you figure out an issue if you come to him. However, he does not really know how to explain the material. For me, his lectures were useless and his powerpoints were not helpful either. I would recommend you read the textbook for notes and to get ahead as much as possible.

Don't come to class thinking you will get all your notes written. you will fall behind. Read the textbook and do notes ahead of time.I never listened to this lectures or used his powerpoints because they were not helpful and were only confusing. Instead, I came to class and ignored his lecture. I would read the online textbook and write my notes.

He is nearly impossible to reach. If you are having any issues with anything related to the class, he does not do anything to help. I can't read his handwriting. Take someone else.

He had very hard tests to the point where the entire class got a curved average of 20% and he had to give a full class a retake. lectures are very confusing due to his pronunciation of certain words. He also ignores questions and when he does answer them he is confused on the question is about. he will also rush content which leaves you confused.

Worst teacher I've had for chem. None of his lectures tie to the homework or questions he asks during the class. The microphone he uses distorts his voice so if you sit in the back of the lecture hall, you're screwed. Attendance isn't mandatory but if you miss a lesson where he uses the iclicker's you get a 0/5 for the number of questions missed.

Please for my own sake do not take this professor. It make seem like you have no options but please pick someone else! He's almost impossible to understand, attendance is graded by pop quiz questions during the lecture, the exams are horrible NO RETAKES, the only thing that will save your grade is the hw that takes 5 hours to complete on a good day

As a STEM major coming into GMU with a 4.2 high school gpa, all of my classes been doable besides this class. Fayissa is the worst professor i have ever seen. unless you sit in the front row you will not be able to hear him, or understand his accent. u WILL fail some exams. class average for the first exam was 52% the average of the second was 40%!

Lectures hard to understand, he does not communicate what is on the tests properly. I would recommend to not take him even if he is the only option, it might be better to take chem later on.

I would rather jump off of a cliff without a parachute then ever take this class again. If this man was the last person alive that could teach me, I would still not retake this class. Do yourself a favor -- do whatever it takes not to take this course.

Tests do not correlate to what he "teaches", or the hw's. the class average is consistently an F for every test. Unbelievably awful professor who is very hard to understand. would not recommend to my worst enemy.

The course was extremely difficult due to the teaching style. There was a large disconnect between tested material and learned material.

DO NOT take this class. Especially if you are a Chem major. Dr. Fayissa is, for one reason or another, not equipped to set you up for success. As a 4.0 sophomore who is decent at things like calculus and physics, this class was an infuriating nightmare from beginning to end. I would wait to take chemistry instead of taking it from him

Wouldn't recommend. Tests are shockingly hard, and the class average is almost always very low. His lectures are pretty mid and his accent kind of makes it harder. But you have to come to class because he has iClicker quizzes. I'd try someone else.

Please take another professor!! His lectures were absolutely useless and ended up self studying the entire course. Only went to lecture for the iclicker quiz questions which were random and impacted grade. Class average on exams were very low usually around 50% and only got worse. Tests were also usually around 20 questions so easier to fail.

DO NOT TAKE HIS CLASS! This is the absolute worst teacher for CHEM 211. His class is very lecture heavy and the slides are often not helpful. He gives ~5 question quizzes most class periods on things you have just learned and had no time to study beforehand. The tests are super hard, but there is a large curve at the end of the class.

Got the first test in my life that I ever failed. The average for exam 2 was a 40%, and he had the audacity to say it was our fault. Gives no time to take notes. I thought I would enjoy chemistry but this guy completely ruined it for me. Lectures are pointless, I learned the curriculum through the homework and you tube.

Fayissa is nice and quickly to emails, but that is the only good thing. Very hard tests, for the first 2 exams was 40%. Lectures are a waste of time, he just reads off the PowerPoints and will give an iClicker quiz immediately after with no time to respond. I would never take him again if I didn't have to.

Probably the most miserable learning experience i've had. He's a nice guy but he really can't teach and there is a large disconnect from what he "teaches" and what is on the test. Test averages are 50% for most exams. HW takes 2-3hrs each week. The only reason I passed this class is because I taught myself and studied insanely hard. DO NOT take.

when his test averages were 30-40%, he put a letter from a child prodigy on the projector to illustrate what an amazing teacher he is, and told us all we weren't putting in the work instead of asking himself why so many students were struggling. chemistry can be intuitive and fun. take another prof so you can get the most out of it

This has been one of the most miserable experiences of my college life. I would rather jump out of a plane than take this man again. Please save your money and sanity and take a different professor.

Prof. Fayissa is nice, but he sadly cannot teach well. He speedruns through his presentations and gives 5-question iClicker quizzes on content you just learned (and is surprised when the class averages on the exams are low). Only reason why I got an A was because I effectively had to self-study the course plus the huge curve at the end.

Horrible professor, avoid at all costs. Exam averages are terrible, around 30-40%. He warns against relying on the curve but generously curves grades at the end, causing unnecessary stress. His teaching is useless; lectures are mandatory but a waste of time. He's unfit to teach general chemistry, speaking at an overly advanced level.

One of the worst professors ive had. Second exam had an average of around 40%, after which the professor blamed the entire class for not putting in enough effort to prepare for the test. The lectures are bad as he explains stuff like the average student already has a phd in chem, and quizzes the class on the stuff that was just learned.

Fayissa is at it again at proving how being the head of the department of Chemistry doesn't mean much when your inability to be prepared to teach a class shines through way more. Students wrote the syllabus practically, didn't have the homework, didn't know when exams were and how long they take. Oh, no camera? No attendance. Have fun with that.

In the 4.5 years I've been doing undergrad, between various schools, Dr. Fayissa is the single worst professor I have ever had. When asked to clarify concepts in class, he lists why he put the example in the lecture and moves on. The class average on tests is 40-60. He hasn't responded to a single email I've sent and isn't available in person.

If you want a prof that is organized, is hard working, and cares about making sure students are on the right track, he isn't the one for you. It's a fend for yourself kind of course. GMU Chem department is notorious already and this guy is the reason. If you're not already a straight A student, pass this professor and DON'T take Chemistry at GMU!

When asking for help, I was met with unclear or even nonexistent answers and no help from the professor whatsoever. I had submitted learning accommodations that had been approved by the school, however the professor did not respect the accommodations. The lectures were very hard to follow and he always went at his own pace ignoring the students.

This professor is failing students with his incompetence and surface-level lectures. Multiple students, including myself, found it hard to get him to respond to emails, even when you needed his assistance. I did all the homework, attended all lectures, and paid for tutoring, and I barely got 15% back from this guy. Most miserable experience ever.

PLEASE LISTEN TO THE REVIEWS! UNDER NO CIRCUMSTANCE TAKE THIS CLASS! I took this class because it was apart of my requirements, I saw the negative reviews but I still thought I could handle it. I would spend over 8 hours on one assignment, there are 4 exams, each worth 20. This class was a waste of time and money, PLEASE TAKE ANOTHER PROFESSOR!!!!!

He is difficult to reach even when you're struggling, our class exam average was like 46%. Which says a lot about the teacher. Most of your grade depends on exams, which most people fail, class exam average was never higher than a 65%, responds to emails very late. Honestly, he doesn't even teach, he just reads off a slide the whole class period.

just don't take him. I can't understand half the things he says, he does an iclicker quiz every class, if you are absent (even with doctors note) he won't drop the grade from the one you missed. 0/10 do not recommend - current student of his

He is very lecture heavy without actually teaching anything. He reads from a screen, writes stuff down in the board, and expects you to know everything and do hard problems in 2 minutes or less. Any time you email him, he never replies and doesn't necessarily look in his students best interest, just comes in, reads slides, and then leaves.

im the one who wrote the previous review i take back whatever i said

Can't understand him at all, he does problems on the board but he doesn't explain at all, expects us to know everything perfectly before lectures, and exams averages are so bad. Don't take chem with this professor if you care about good grades and actually understanding what you learn.

DONT take him if you want to have a decent grade in chemistry. Lectures will put you to sleep and aren't even comprehensible, plus much of the content on the exams is only touched upon briefly or isn't discussed at all. To give an idea of the difficulty of this class, at the start of the semester the hall was full, by the end only 1/3 remained.

Accent is hard to understand. One attempt for exams while other teachers give 2. Quiz every class on new content. Your best bet is to read textbooks by yourself and then do the ALEKS assignments again for test prep. Although this is a hard class with a hard teacher, an A is possible. Also he curves at the end even if he says he wont.

DO NOT TAKE THIS PROFESSOR. He teaches at a graduate level yet teaches undergraduate course work. His tests barely align with content covered in class and he does not curve. I spent at least 15 hours a week studying and it was a 3 credit class, do not take a class that is going to give you more work than it should.

He's a nice professor, but unfortunately, he has a lot to improve as a teacher.

Bruh don't take this professor.Even if you have to wait one semester to get a good professor if the classes fill up,don't take him! don't be cocky and think you can do it, you won't, you will waste tuition money.I'm highly positive I'll have to retake this course and I spent 5 days studying for his exam,so I tried..Ppl rating him well are lying lol

Doesn't know how to teach

Had to self study the whole course because he cannot teach for the life of him. He had massive mistakes in almost every exam but did not correct them. He let people cheat on 2 exams and didn't give them 0s because they didn't cheat on the final and 3rd exam. He does not care about his students grades at all. But he is a nice guy.

If you care about your mental health and sanity listen to reviews and DO NOT TAKE THIS CLASS just wait another semester to take this class with another professor (I would put this in bold letters at the top of the screen if I could) head to patriot web rn and look for another professor please!!!

He is a nice person, but horrible at teaching. I don't understand why he is the only professor who is teaching this course; it feels like a nightmare that can't be avoided. The quizzes are full of unexpected questions, and usually require equations that have not been practiced in class. HARD homeworks too.
