black guy with weird hair, funny sometimes but boring most of the time. talks about movies, says math are crap. what a long notes, and.. huh? he keeps saying huh..

Overall VERY LAZY TEACHER. Loves to say WHATEVER when teaching. VERY VERY VERY! UNHELPFUL in his office hours. He tries to help you as LAZY as possible.

he is so lazy and does not have office houre,does not help...please hire somebody else for teaching linear algebra please...

The second worst instructor next to MR. Gosal! No enthusiasm what so ever. At times I felt like there was an ice cube writing on the board melting as time passed. He is such a cold instructor. Makes things very unclear and has very bad midterms. One question was in form of some food recipe, students thought the name of the food was the formula, so

No Comments

This was the worst teacher I have ever had next to one teacher I had last simester. Never take a class with this guy if you need motivation in any way from a prof. This guy just really doesn't care about much at all. And he is so far out there that he couldn't explain pythagorum in under an hour.

Can't teach at all...I try to give math a shot, and he made me regret it! He's rude and is a know-it-all! He thinks less of anyone who doesn't like math (which is a lot of people)..OVERALL JERK

I got a A in calculus 1, but a C - on his class. GPA killer!!! He is not supposed to be a teacher.

this guy finished course material one week before school ends. the problem with him is that he expects us to be ALL SMART! WITH SOLID CALCULUS/MATH BACKGROUND.if you ask "stupid question" he will EMBARRASS YOU! i would not recommond anyone to take his class unless you LOVE math and you are super good at learning math! he's more like an AP teacher..

He's not helpful.

Jang is very cool in his own mind which makes him anti social and not very likable. He gives you 60% of the class grades for free and makes the final impossible. If he could just stop dragging his feet everywhere, perhaps tuck his shirt in, and perhaps pretended to care, the world would be a better place.

The worst teacher I have ever had. Thinks he is way too cool and expects you to "know" everything. All he did was discuss how he is so smart and his taste in music is incredible. This is a math class, not a history class on music from the 70s and 80s.

Better hope the class has no flies. Be ready to to study outside of class.

Class wasn't overly difficult, just practice and you should be fine.

This professor may have some personal issues w neglect. Has someone hired kim jung anh to teach at Langara??!

Terrible math teacher, tough grader. He will deduct every single possible marks. Don't waste time and money to take his classes and get a poor grade to destroy your whole GPA.

Terribly hard teacher. His lectures very boring and the final exam is ridiculously hard. Makes us memorize too many theorems and proofs. 1Tests are mostly conceptual and intended for students with a strong background in calculus.

Don't take his class if you have never study calculus. He is known as the worst teacher in Langara. He teaches nothing no HW. His tests are only easy for students who have studies calculus before. If you are a newby in calculus, don't take his class. Half of his student dropped his class. I register just because I really wanna rate this s**t.

this guy is not good. no homework for mark. The questions of his exam are stupid. He does not give you the questions that you practiced before.

He teaches math like he is teaching philosophy and history xD

I've never had a problem with math, until I got this instructor. He tries to get people to answer questions in class so that he can mock them in front of everyone (didn't happen to me) and is very rude. He assigned the even practice questions in the text, and then tested on material that was only covered in the odd #'s, and was not taught in class.

such a good teacher

I won't recommend

He teaches 1 question per hour. The slowest teaching I've ever experienced. I remember one day he spent half an hour to talk about cinema... He thinks he is a genius.. so he acts like a weird guy. he always puts up his hands with no purpose...

He is my nightmare. I shouldn't take his class. He really does not know how to teach.. he teaches so slow. And he teaches a lot of unuseful things...

I love math. I did pretty well in High school. But this teacher never teaches well.

One of the most unkind and unapproachable profs I've ever had. He very clearly looks down on first year students. Often goes on long tangents that have nothing to do with math. Has been late to class multiple times, including the midterm. Overall an unpleasant experience.

He is a good teacher but not so patient. He prefers spending his time on his own research instead of his new students.

If you didnot take this course before or have a background of Calculus, I won' t recommend you to take his courses.

Marks come solely from quizzes, midterms, and final. No credit for textbook work, work on Web Assign, or participation/attendance. He is consistently 5-10 minutes late for class and goes off topic easily. He makes unethical and disrespectful 'jokes' about students. Avoid him at all costs. He makes you feel stupid which a professor should never do.

Probably one of the worst math teachers at Langara. He was the only teacher for math 1153 so I had to take him but if you have a choice, PLEASE AVOID AT ALL COSTS. The midyear was decent but the final was extremley difficult you would rather not take it cause you already know you're gonna fail. Half the class didn't even pass the course. AVOID!!!!!

Honestly Jae does teach but only teachers the easy exercises and expects you to know the harder questions he puts on the final. He tells the students to participate but if you say the wrong answer he makes fun of you. Not approachable and final was so hard, it was the reason I failed this course.

over 2/3 students dropped out. This guy likes to talk about his life and how he's a genius for creating stupid techniques. Doesnt assign questions so you dont know what to expect on midterms. I got perfect on all the quizzes but got 40% on the midterm

He loves math but not teaching (VERY unapproachable). Lectures either correlate with homework/quiz/test or not at all. First midterm class average was 47%. I lasted 1.5 months in his class before dropping. I swallowed my feelings every time I visited his office (5 times in total), and each time he would say something negative to me. Choose wisely.

Worst instructor ever. Don't even consider taking his class because you will be ended up dropping out. I can tell that he likes math but not his students. He is a sarcastic person, so beware.

He is the worst math instructor I have known so far at Langara. No kindness, sympathy and empathy. A lot of students drop his classes. Rude and unapproachable. Avoid him at any cost.

The materials in his lectures do not match with the level of the course. He teaches tough things and does not give practice questions before the tests. His tests are more difficult than what he teaches. Many students drop his class. Unapproachable and helpless after class hours.

I dont know why this insane guys rating is 3 out of 5. Wondering how come he got hired by Langara. Doesnt teach very well but just a tough marker. And extremely hard exams. If u think hes not the worst because of rating, dont trust this rating. Dont waste your money and time to lower your GPA.

Avoid at all costs.

Avoid ate all costs. He does not respect students.

Avoid this professor at all cost dont even take his class if other are full because eventually you are gonna lower ur gpa Quizzes are easy but the real game starts when you get your first mid term and course keeps on getting harder He Terrible guy talking about all that crap that revolves around him instead of teaching properly

Avoid at all costs. Never seen such a bad prof in my life. His voice very low, if you want to hear him, you have to sit in the front. He is actually overrated, not even 2.9. I had way better profs who had lower rating then 2.9.

Terrible prof. Angry, mad at life, makes fun of students. Spends literally half an hour (in 1 hr class) ranting about non-math related stuff like too easy school systems, and how people ask too many questions. His lectures are so obscure so you have to read the textbook, but his exams are unnecessarily hard. Idk how he has 2 good ratings plz fire

Avoid at all costs. His tests are extremely hard and does not align with what he discsses in class. Very hard to get grades even in simple questions. Thus, it is almost impossible to get feedback as he gets mad at you for asking anything (in class, about exam, on one on one, etc.). Moreover, he always judges people and very hard to hear him.

just dont take take his course

Don't take his course terrible teaching

I don't really like his class. His midterm is not related to the lecture.

horrible do not recommend! he can not teach im sorry but its the truth

2.8/5? Are you kidding me? Jang is the worst lecturer I have ever seen. He does not know how to teach at all, and neither does he know how to question students in exams. Can you imagine that the average of midterm 1 is 51% and a half just withdrew after that? Students are not stupid. He should be kicked out of college. Avoid at all costs.

There must be a reason, other than being an instructor, that can explain why he is not kicked out. He is way far from being a good instructor, far from being an instructor. Low voice, no respect. If you check the course list of 2020 summer which is crazy, you can see almost all the other sections are full, but his are always available. Guess why.

one of the worst instructor in Langara , he spends his lecture time talking about crazy stuff rather actually teaching , the worst is from the beginning of semester he decides who is gonna fail his course no matter how hard you try , his exams are just 5 questions if you miss sth you would loose a big junk of mark.

not enough exercise. the test is impossible to finish. if you want to pass you have to work really hard.

His sound is low and the lecture is terrible, you will learn almost all by yourself. He never posts his note online for studying. The first midterm average is 35%. If there's a tag saying "not caring", I would select that. I'm just going to say that other comments about him that are rated "1/5" are all true. Just one word: Run! Run, my friend.

I won't say he is a bad teacher. He tries to make math class less boring. You have to be independent because he won't give you any practice. The grade is solely from 4 quizzes, 2 midterm tests, final test. I already took Calculus in high school, got and A. His test is not hard for me BUT the time he gives for his test is not reasonable.

He is the worst professor ever. I would strongly recommend you to not take him. he doesnt care about students and keeps on talking bs. He doesnt even have an atom of cooperation. DONT EVER TAKE HIS COURSES.

Worst professor. Avoid at any cost. Doesnt know how to teach at all. Never would give any instruction for quiz or midterm for second time even if you ask 2-3 times. Not at all co operative.

This is the second time I take Cal2. He does not care students at all. He doesn't like students to ask him questions. He teaches very fast, there are only 1 or 2 examples on each topic. The first midterm average was 35% and he didn't think that is a problem. The exam was not able to finish it. It was very long but easier than Miss Nguyens exam.

Never ever choose him! I again say NEVER! he literally solve 2 to 3 que for each topic and thats it! questions in exams are from idk where, which he never taught us. His voice is hardly audible and you cant understand properly.

The class is based on 4 quizzes, 2 midterms, final. He never posts lecture notes, lecture videos, practice exams, quiz schedules on D2L. I'm pretty sure nobody wanna take his class again but he is the only one who teaches Math1153 and 1253 at this time. You better avoid him at any cost or take Math 1171 instead. Trust me!

if youre doing the 1153+1253 path just dont do it, take the mdt or another math course to get prerequisites for 1173 or 1174, jae is possibly the worst prof ive ever had simply because his lectures are super dry and he also makes the quizzes and midterms too difficult for an intro to calc course, honestly shouldnt be teaching anymore.

I already took Calculus in my high school, got 90% with it. I'm confident with my Math knowledge. He seems only does teaching for his living. Dry lecture, talk about non-sense things in his class Lecture: Walkthrough some examples of new chapter. Done the lecture Test: Non-sense heavy (compare to his lecture) with unreasonable given time.

Only cares those students who would respond him in class. And he could spend more time of the class on talking about what he is interest.

He is the worst of all. In the lecture, he refuses to provide materials regarding tests. And if you ask him questions, he will tell you to ask other professors. His tests are made for not letting students pass. He is proud of his class average being below 30%. He will tell you that you are not talented to learn anything, pack your stuff and go home

He is the toughest professor I have ever taken classes with. His quizzes including midterms and final exams all were super difficult. His lecture materials dont match up with the testable materials. Hes a super tough grader, not approachable at all. He gives lots of questions in less time.

The toughest prof I have ever taken classes with. His tests all are super difficult, refuses to provide materials regarding tests, if asked questions, he humiliates students, His tests are targeted to fail students, wastes lecture times on ridiculous & nonsense Off-topics and on zoom inviligating rules which he was unhappy about. Dont choose him

He gives such little time for the exams/tests he gives. I took him last semester and dropped it hoping it would be a different prof but unfortunately he was the only one teaching. Also, he takes a LOT OF marks for no explanation; yet he doesn't give enough time???? Anyway, try to avoid him as much as possible if you can :/ goodluck

This is a classic example of how a bad teacher mislead students. His attitude toward students is disrespectful. The reason why he teaches students is that he wants to insult students. Enjoy your life and never take his class.

The worst professor I've ever had. He should probably consider quitting teaching because he is the worst at it. This guy has zero empathy for his students. He thinks all his students are God of Mathematics. Listening to his lectures is the hardest part of Calculus. He always goes off-topic and he refuses to provide appropriate course materials.

Talks about random stuff all the time. first quiz average was 21 %. learn it all on your own.

Avoid taking his class at all costs. His 10 marks quiz only has 1 question, the most difficult one from the chapter. He does not even gives marks for half correct answer. Take his class if you are exceptionally good at calculas. Lectures are way off topic. I have taken four calculas courses and he was the worst.

Doesn't say what you got wrong on midterms. You're going to have to learn on your own!!

This class is based off 4 quizzes 2 midterms and a final exam. Jae rambles on about random things in class when he should teach calculus instead. The lectures are also extremely boring. He also marks extremely harshly and does not show why you get marks taken off. Look at his name and run.

Lectures are terrible, only 2% of his classes contain any useful information. His exams are generally easy but some questions are weird. Was much better off doing problems on my own and consulting the internet, and I'm only passing because I'm teaching myself. Don't take him unless you have extreme work ethic and discipline.

Jae is uncaring and disrespectful towards the students. He gives the most basic examples in class only to throw the most ridiculously complicated problems he can possibly find. Along with that he gives too little time on exams and quizzes and loves bragging about low exam averages. Avoid him at all costs.

The worst professor I have met.4 quizzes and the highest average is 60%.2 midterms, one average is 50% and another one is 37%. He teaches the simplest things from the textbook and finds difficult questions for tests. He gave three exams in 2019 one week before final, and gave answers 2 days before final, then he says some answers are wrong. Lmao

What the average lecture looks like: 50% Random topic rambling. 20% Talking about how you were "taught wrong" in high school. 30% if you're lucky is actual teaching and relevant to the course.

Avoid at all costs - Rude communication style. Qs are a burden, no intent to explain - Prepare to self-teach material - Exam issues: heavy time restraints, Qs not covered, stringent marker, no feedback - Prefaced 48% midterm avg by relinquishing himself of responsibility - Uninterested in student success Jae limx+4(3/(4x)^3) - Jae -

Worst prof ever doesnt explain anything rambles on for half the class about irrelevant things. Midterm 1 avg 33% midterm 2 avg 33% final avg 42%. Doesnt care about students, barely responds to email, and if you ask a question in class he will find a way to make fun of you but still wont give an answer

just rambles about random things for the entire class does really "teach" just talks. his exam averages are below 50% I would highly recommend you to run as far away from this guy as you can. I have no problem with him as he seems to be a nice enough guy but he sure isn't a good teacher. You won't learn anything.

Class is rigid. Only one or two sample questions. Difficult exams and questions are not even mentioned. Doesn't care about students at all. The average of two mid are 32% and didn't exceed 40% in Final. If you are a good student and want to get a high GPA, he will definitely make you miss UBC or SFU. I got A+ from 1173, but only D in this course.

Worst math professor Ive ever had. Does not care about students. Makes you look dumb when you try to ask a question. Most of his lectures consist of him rambling about random things. If you take him be prepared to learn everything by yourself. Dont recommend him at all, and especially if you struggle with math

The worst person and instructor i have ever met. Teaches 1153 and think he is talking to math PhD. Hope you dont have any questions cause if you do he will make sure you know it was a dumb question. I absolutely despise this man

Do not take this prof. It's honestly better to drop the course and try to get another prof the next semester. If you don't trust me, good luck you will need it.

Horrible. He blames the students instead of his own inability to teach a coherent lecture. Take his course if you want to ruin your GPA and your chances at transferring to a university. His grade breakdown consists of a couple tests, all of which have so few questions that if you get a few wrong, you basically fail .

This guy is dead for me. This guy has less time left than queen elizabeth. So don't take this course xD

Half the class dropped out. With 12 of us left the midterm average was a 43 and he took 0 responsibility and basically claimed we were all incompetent. We had the higher midterm average of the 2 sections.

Lectures give little to no useful information, meaning most content has to be self taught. Quizzes and exams have so few questions that mistakes are fatal to your grade.

Doesn't teach concepts very well, and makes exams extremely hard. This guy is so uncharismatic. Run if you can!

One of the worst professors I've had in my life. The lectures were uninformative, the tests were unfair and Jang even lied about what would be on one of the midterms. It was so bad our class even began the process of contacting the LSU about how unfair his exams were in hopes of forcing the department to scale the grades. Avoid Jang if possible.

What a terrible instructor! I have never met a teacher like him in Canada. His favorite thing to do is to fail students, no examples, no practice, there is even 25% of final exam he nevery talked about in class. Those comments praising him I doubt that he wrote them himself.

Nightmare Alert! Avoid for Your GPA's Sake! Let me tell you, he is an absolute nightmare. His personality is just plain bizarre! The teaching approach? Total disaster! He will ruin your GPA and all your university transfer plans. Do yourself a favor and don't put up with the frustration and disappointment he will bring

pick another prof if possible

It's sad to see that Professor Jang appears to favour girls over guys when it comes to helping students. This kind of gender bias creates an unfair learning environment.

The ratings were true :skull:

In brief, he got a really strange personality and his tests and grading are just as odd. Best to avoid!

Don't take classes with him if you want to pass. He is a strange guy and does not know how to teach. His grading is really tough. He teaches simple questions and gives much tougher exams. He is not energetic at all.

He has a decent teaching style but his strict marking does not correctly represent student's understanding of the topic. Many students (in my class) committed much time to understanding the topic deeply and could do most problems correctly, however, they made a mistake at the beginning (+/- signs, wrong graphing,...), and they received 0.

He is a nice teacher however he has strange personality and his grading schemes is terrible.

Would not recommend Jae. Wouldn't answer my questions and while I did well on his quizzes when I saw my first midterm I decided that it wasn't worth staying in his class. Had friends stay who wished they dropped him. It's really scummy that Langara hides the profs until it too late but its probably better to just withdraw/drop this prof.

No comment

A terrible professor who ruins your gpa completely

If unprofessional and ignorant attitude was a person, we found him. I'd rather eat a large handful of dirt and wash it down with conc. acid than to ever conversate with him. Infamously terrible rep. among all students and profs. School admins are trolling us with this one. Avoid at *ALL* costs. My condolences to the math dept. and his students

Terrible. Avoid at all costs.

Jae is kind of a funny guy. Your mark is based solely on 3 exams and a couple of quizzes, mess up one exam and it's hard to recover. Pretty much all content has to be self-taught as lectures hold little useful information as he teaches the weirdest, incomprehensible methods to solve problems. Stay away if you can.

The class I took was very hostile. Jang would frequently raise his voice, point his finger, and belittle students even for something as little as mishearing which definition he wanted and saying a different one. Very uncomfortable, high anxiety class which made it hard to attend lectures with an anxiety disorder. Only definitions, no concept work.

Not approachable, condescending. He assumes we all already know the material, and explains new concepts as if it is a review for everyone. Would not recommend.

The worst

Avoid at all costs

Avoid.

Wears a mask and every other word is an "uh" or an "um" making it very hard to listen, doesn't talk loudly either so good luck if you sit at the back. His lectures rarely have examples so reading the textbook or watching videos would be better (it's a math class, you need numerical examples to understand). A rock could teach better than him. Avoid.

bro the class avg was 30%... at this point its not the students its def the prof... bro cannot teach. a monkey would be better than him, his lectures don't even make sense half the time. how is bro still employed?

Good: engaging lectures, quiz/exam difficulty isn't bad Awful: marking on T/F or proofs is overly difficult (if you seem to understand the concepts he may dock you 20% of the total exam mark or the whole question arbitrarily), heavily proof weighted, time constrained, impossible question on a quiz (typo) removed it and gave no points. 30% mt avg.

He is the worst professor I have ever had. He is not good at teaching badly, his lecture notes are not helpful. The exam's difficulty level is way harder than his teaching, and he's not kind when the students ask questions they don't understand. I wonder how he's taught math at Langara for over 10 years. He doesn't deserve to teach students.

will not relent to give you a zero for any errors on questions, barely enough time for exams, and doesn't post any practice questions. Exam difficulty is incomparable to practice material; only a few questions to cover whole units and barely any time.

Just avoid.

I do not recommend ever taking his class. Unfortunately he does not explain well. During class, he will pick some random archaic math problem to go over very detailed for 30 minutes and he will rush through some other random steps without letting people understand. When people ask questions, he can get angry sometimes and ask "why didnt you know"

Unless you already have a math degree and youre only here for fun, do not take his course. I dont understand how he still has his job.

very bad, please avoid him

Worst grader I've seen, either no marks or full marks on test questions. I've seen dictatorships with more flexibility with freedom of speech than Jang with his grading. Taking this class was a bigger mistake than the German President's Chancellor appointment in 1933...

Extremely poor behavior. Class was unreasonably difficult due to a lack of teaching ability and poor test structure. Peers often reported feeling sick from anxiety over class stress due to poor treatment. Avoid at all costs.

terrible. not even unstuck ai can help you if u have a prof like him.

Just no words avoid if you can

No words to say avoid if you can.

unstuck ai told me to drop this class... i should have listened. AVOID!

Lectures are somewhat unorganized and heavily focused on theory. Definition questions on quizzes and the midterm are strict, one wrong word can cost you half the mark. He would spend a lot of time explaining concepts, which is more confusing. Quizzes and the midterm are short, so it's essential to practice on your own to manage time effectively.

Its better to buy a textbook to study and practice by yourself. Literally only need to attend class to write down definitions concepts which will be on quizzes and midterm, otherwise self studying is better than listening to his lecture and be confused

His grading scheme is hilariously strict. You're usually either simply right or wrong, and there's no in between, no partial marks. He teaches like a robot that has no awareness of his surroundings or his students'.

On quizzes or exams, It does not matter whether the principal you used is correct whether from the textbook or notes. If you show your work correctly and get the correct answer, IT DOESN'T MATTER. Marks WILL be taken off if you do not solve the question like Jang. Small mistakes will cost you avoid at all costs @anyone who wants to learn or do well

Do not enroll in any of his classes if you care for your mental health. I use to love math and this guy completely ruined it for me.

Please do not take this person can really ruin your transfer plan.

The lectures were not very engaging and often felt unorganized. Explanations were sometimes unclear, and it was difficult to follow along without relying heavily on the textbook or outside resources. Assignments and exams didn't always match what was covered in class.

Stay away. Even if you need this course and are desperate, pick a different prof

The dude should be in a research facility instead of teaching.

Get ready to walk out the room learning absolutely nothing! This guy honestly has no idea and I am awed as to how anyone learns anything at all from this guys lectures. He rambles all class and explains nothing of what he is doing. Works on the board silently and expecting you to just understand.

Not a good teacher at all, do not take his class. He writes stuff on the board and expects us to understand after saying a couple of words. He is off topic half the time and during the first day, "warns" us about how many people have failed his course. Save yourself the trouble and take another prof for this course.

He's a questionable prof. When he handed back one of my quizzes he called me stupid. He makes you question your ability of how to do math. DO NOT TAKE IT WITH HIM IF YOU WANT UR MENTAL HEALTH TO BE GOOD. He writes the questions down and solves them while explaining but erases the solutions right away.

Not approachable at all, and is unempathetic towards students. Tests are ridiculously difficult as well. Please avoid him at all costs.

Saw him in the halls the other day and he cussed me out under his breath while walking by. I asked him what he said and acted like he said nothing. The character of this man is inhumane, he is an animal who hates anyone that he teaches. If you don't want to learn calculus and be disrespected take his class.

This professor doesn't teach at all. He just faces the board, mumbles to himself, and never engages with the class. His explanations only make sense to him, so everything had to be self-taught, which was really tough with other classes. Taking this class felt like a complete waste of time and MONEY.

If you have plans to transfer to UBC, this man right here will be the death of all your hopes and dreams.
