Learn some english, is a crappy teacher

No Comments

I am a strong supporter of standardised english proficiency testing...FOR PROFESSORS. This guy wouldn't be able to order from Mcd's with his accent. "I want aer hapee meear with no flies, and extwa mayunairse. Forget fob, he's sotb.

The test are easy enough, although the multiple choice can be very tricky and worth too much. As a teacher, he is really funny, but he should learn to teach. Is it just me, or are all math prof incoherent? easy if you can learn it yourself.

i can't understand what he's teaching and saying. sometimes he didn't answer students' questions

HORRIBLE TEACHER, I don't care about his accent but not only that he cant communicate but he is also RUDE and disrespectful.

This guy is horrible at teaching. He has the same name Lan which is my first name but Lan is his last name. I was expecting good things to happen until he had to fail me. I just hate the way he teaches and explains things. Really a lack of help for success. Study the notes first, yeah right

From the sounds of it, this guy needs English lessons more than fish need water....

I wish i knew wht he says in class :( god knows how ryerson even thot of hiring him as a prof...ryerson is NO GOOD!

Oh... my... god... He's all over the place, he ONLY gives examples and WON'T explain WHY he's doing what he's doing UNLESS you ask... he CAN'T teach... i've learned the entire class by myself, no thanks so him.. at all.

Mr. Lan would have been very helpful if only he understood what the student's question is. Otherwise he is a great teacher. I just didnt like it when he raised his voice at me when I went up to ask a question.

A very not clear prof...his jokes are boring and I just keep laughing at him not with him....a terrible accent and bad teaching...he write so small on the board and doesn't know how 2 use the marker...after all his grading is not fair...but his exams are so easy. I believe I can teach the class instead of him and be better than him.

Can't teach

Strongly recommend that you avoid this teacher. Very inconsiderate, does not help students, does not answer questions, avoids students, dismisses students' questions and generally tries to do as little work as possible. Currently still taking the class, however nearly all of my learning is done on my own time. Horrible waste of $1000.

This guy is rude. I had the other math prof but he ended up taking my question during the final.. he couldn't even answer a simple yes or no question regarding a concept. It makes me wonder how helpful he was to his actual students since I got absolutely nothing.

He was absolutely brutal. Was hard to understand and wouldn't properly answer questions. Our class average was around 45 after the midterm and he refused to curve it. I was one of the few students who did well but only because of the math help in the library.

The bad: Spends forever on very simple concepts, then rushes through the complicated topics, never explaining them properly. Plays favorites with other asian students. Unable to teach and advocated bland memorization. He was "teaching" on friday and then we had a final on monday, when every other prof finished a week early. The good: None.

Poor lecturer. Difficult to understand, does not clarify concepts well when asked, long winded, and uninteresting.

Very poor professor overall. Teacher can barely orate in English. Does not understand questions students ask and thereby cannot answer them. Even yes or no answers to simple questions elicit responses indistinguishable from Cantonese. Is not aware of mathematical conventions in English and so makes lectures difficult. Seek another professor.

He's not helpful whatsoever and extremely rude. Won't give you the time of day if you are going for extra help or further explanation about concepts

Very lazy, and hard to understand (english) and still prefers oriental students. Who puts multiple choice in midterms and exam in a math course. The course cost over $1000 and he is too lazy to mark them

He " teaches" the absolute bare minimum of the material. If you do not need math in the future and this is the only course you'll ever need to take, he is fine. You will ace his incredibly easy exam and be on your merry way. But woe is you if you like math and plan on having a career in it. You can't teach what you don't know, right "Dr" Lan?

Easy class. Literally ripped questions from the textbook (which he wrote). However, he doesn't teach many things. We didn't learn Eigenvalues at all, for instance, and even though I scored well in his class I find myself having to do a lot of background reading for vector Calculus.

I will not take any courses with this professor again in my life. First he is very disrespectful to students, secondly, his teaching style is extremely poor and disorganized. What concerned me the most is that some very important material were skipped which will show up in the future courses. Take this course from other professors instead.

Definitely will need the textbook as reference because his teaching methods aren't the greatest. Very Very Very difficult to understand and often gets angry when you ask him to answer a question or to clarify a question. Assumes all students learn at the same pace and doesn't accommodate for much. Do not recommend.

His "book" on linear algebra is verbatim copied from other sources, with only the easiest examples left. All challenging material/theory has been removed. This is pretty much what this professor is: a shallow shell with a cavity where knowledge should be. A prime example why tenure should not be given based on seniority. Worst RU has to offer.

The worst math teacher ive ever had.

Unless you come from the same cultural background as Prof. Lan, there's no way you will understand him at all. His midterms were decently fair, but the exam was next level hard. His textbook is a ripoff, I paid 30 bucks for an early edition instead of 100+ for the newest one. The textbook is full of mistakes but somewhat decent at actually teaching

you cannot understand a word he is saying unless to come from same background as lan

Cant even hear him or see what hes writing Class of 200: no one understands him

Horrible teacher. Homework did not relate to midterm or final. Claimed if you didn't do well on a midterm or final it was because you didn't do the homework or study -which is a lie because homework was apart of our mark. Would get 100% on the quizzes, but would fail the midterm. Cannot understand a word he says lol. Avoid at ALL costs

this guy has terrible hand writing and a super thick accent. The textbook he wrote himself is down right deplorable tons of typos and a lack and every evidence of steps or what to do making it impossible to learn anything from him. If you have him swap to any other prof you can ASAP

Requires that you use his $140 textbook because he assigns homework from it. It is riddled with errors everywhere. Hard to follow accent. Adds surprise material to a test that he spends 1 hour before the start of the test to explain. Does not give sufficient time to complete the test & submit it electronically in the current Covid-19 times.

terrible prof whos textbook is full of typos and mistakes and and will regularly grade every single midterm and lab you write wrong and you have to correct it yourself and then force him to change the mark pls never take this prof, its the biggest mistake youll ever make

One of the worst profs I've ever had. You MUST buy a textbook which he authored with a lot of errors and incomplete/incorrect sol'ns. Prescribes endless homework that is sourced from his "textbook" and takes 4-6 hours depending on which chapter it is. Since his textbook is abysmal, lecture attendance is required except you can't hear a word he says

He is the worst professor I have ever seen so far. I cannot understand a single word he is saying and he doesn't post class recordings and lecture slides to help us too while other courses do. His teaching style is also the worst.

The guy sees his students as walking money bags; he wrote a mistake filled, badly written book that is mandatory as it contains the homework questions, of which three dozen or so are due every week @1.66% of your final grade per week. He also does not care about international students as he banned lecture recording even for those attending at 6AM.

No offence, but he is the worst professor ever. He also makes you buy a textbook which has a lot of mistakes in it and he was the one who wrote it. And I couldn't understand a word during the lectures due to his heavy accent. In general, get ready for a lot of self studying if you want to take a class with him.

My man makes you buy a book for 140 bucks which has more typos than someone drunk texting. He doesn't record anything and doesn't post anything so if u don't pay attention 2 hours consecutively at 8am then get ready to depend on the book he wrote and MADE u buy which also is a bigger mistake than taking this course.

He is by far the worst professor to date he forces us to buy his book which is complete ripoff and not only that it is filled with stupid mistakes that make you want to quit. Also in 2021 where it is still online he refuses to post ANYTHING from the lectures so if you live in a different time zone you can kiss your sleep or your grades good bye.

Makes everyone spend $200 on his textbook, homework is 10% of your grade so you have to buy it and you can't get away with an earlier edition. Book is riddled in typos, basically just wikipedia definitions, no explanations of concepts, such a joke. Weekly homework can be a lot and he doesn't drop low grades. Also found him to be pretty rude.

Bruhhhhhh this dude is an actual clown. Be prepared to not understand a single word he says. He is very rude, diverts questions, he is a

Being a first year engineering student in Lan's linear algebra class, I have taken note of the countless flaws Lan has including:Terribly bad note taking style, does not make slides, or record lectures, makes notes on scrap paper with VERY bad handwriting and distribution across the paper he is writing onforces students to write his own notes down

Dr. Lan is very unorganized and inconsiderate. He has a thick Asian accent and illegible writing, making it difficult to understand his lectures and his notes. Additionally, he writes his lecture notes on loose leaf paper and does not upload his notes and when writing on the paper, he does not follow a set order, so he may go from bottom up.

doesn't record his lecture or post his slides. i recommend either recording his lectures on your own on studying from him poopy textbook than you have to pay for. doesn't care about his students at all and whenever u ask him a question he just says refer to the course outline. good thing the subject itself is easy, the prof just sucks.

Had to buy the textbook he wrote for this class. It is full of typos and explains most concepts in a very roundabout way that makes the course almost incomprehensible. In addition, huge amounts of homework questions are expected weekly.

Unclear lectures & notes based on an unreasonably expensive textbook he wrote which was a large waste of money and time to look at. Midterms & exams were never curved even though the average was below 50%. Homework questions were easy and nothing compared to midterms & exams.

He has a thick accent, which makes it hard to know what he's saying. He writes using pen and paper for lectures, but his writing is illegible. He wrote the textbook for the course, which was very dense and expensive. The only reason I did well was because I went to Dr. Majed's lectures instead, and even he had a hard time deciphering the textbook.

This professor forces us to use his own textbook which is very poorly written, formatted and full of typos making it confusing. Not only that, he has a very arrogant attitude when asking him NEW questions that were not answered by previous material. When you ask him a specific question, he tries to dodge it with a one word reply or short sentence.

He's fairly nice, but you get very trapped in this class because it's poorly managed. The entire course was a nightmare. The textbook is mandatory and custom made, and it has a lot of errors and clearly wasn't proofread. It's a shock that a publisher allowed this junk to be published. Makes learning impossible even if you try.

He has a thick accent that makes it hard to understand on top of not explaining things really well. He wrote the textbook himself in which there are many, many mistakes and is hard to follow. He keeps basically harassing people to go up to the board and do an example, after which he'll be very mean if you do a mistake.

He overcomplicated simple mathematics and made it difficult to understand. He is not lenient with any work and doesn't communicate well. This is made worse due to his thick accent.

Beyond Incomprehensible. Expects students to outrageous mental math while barely being able to do it himself. Wrote the mandatory textbook, which has so many errors Stevie Wonder could point them out. Doesn't know how to answer questions, writes notes too fast and overcomplicates simple vectors. After a week his lecture hall is empty for a reason.

Most awful professor for the toughest subject!!!

I never had this guy, BUT apparently ive heard he is a really bad prof and his textbook for lin alg sucks cuz it has so many mistakes in it.

sure he thinks he knows what he is doing during lectures but tell me why the textbook that HE MADE has so many mistakes in it

Man skips office hours. He makes you pay for his book which somehow has been published 5 times?? So many mistakes. He does not deserve is 250k+ salary plus book earnings. You would think at least his lectures would be good right? Nah, not true. Good luck with this man.

He does not show up for office hours. I ask him a question during class and he got angry. I did not understand what he was asking, so I opened his textbook (he wrote the book) and he yelled at me.

Harassed a student into dropping the course. He goes around the room with a marker begging students to solve problems. He is not helpful. Had covid symptoms and was not lenient about it. Would not settle for anything les than to first go to the doctor. I just wanted an assignment worth less than 1% to be ignored.

By far the worst professor I have ever had. Rudest professor ever and doesn't even show up to his own office hours. Terrible person, doesn't even speak English, making lectures extremely hard to understand and doesn't care about any students at all. If you get this man as your prof, good luck all the odds are against you

Think the other reviews speak for themselves but watch out for this prof. He has an extremely thick accent so you'll have a hard time trying to understand him. But on top of that, he doesn't even teach well and is not a nice guy. He practically forces you to buy his textbook saying you'll "fail the quizzes and the course if you don't get it". Awful

Lan was very hard to understand and in turn, was very hard to learn from. The textbook also used in this course was written by him which had many typos and false answers. His handwriting is messy and very illegible during lectures. Overall not a very good professor and you would benefit way more from switching to another professor.

His textbook has so many mistakes, even the formatting is messed up, super annoying for the matrices. He forces you to answer questions on the board; you can hardly understand his writing unless you sit in the front row. All of his lectures are handwritten on the whiteboard, so you have to be in class to get notes. Lots of hw due every weekend.

His textbook sucks, formatting is messed up. His accent is heavy and writing is difficult to read, you have to sit at the very front row to understand both. You have to be in class to get notes because he writes on the whiteboard. Lots of homework every weekend. He forces you to answer questions on the board. Not helpful at all for exam review.

No lecture notes/slides & lectures are very messy/hard to follow. He wrote the textbook which is full of mistakes, & so are the lectures, so good luck learning. He doesn't teach in the lectures, just puts up a question then takes 10 min break while you solve the question alone, when he does solve, lots of mistakes!

Unorganized, terrible textbook, doesn't reply to emails. I don't know what to expect on evaluations, there is no review or practice test like other courses on top of his poor teaching

"check d2l" - famous words from cumquan lawn.

take this course on chang if you can, avoid him at all costs

Textbook that he wrote is riddled with errors and despite doing every single practice question then reviewing and spending 30+ hours studying the material the final and midterm are way harder than the material in the text. I even reviewed previous exams from the TMU archives and Lan's final was way harder than any of the exams in the archives.

Awful textbook that he wrote which he forces you to use, is not even written in English but he used google translate for it. Very hard marker and writes unfair exams that even the other professors do not agree with. All the professors dislike him secretly.

Switch out right away!!! If you have him for MTH141 and you can't switch out, do yourself a favour and just attend ANY other prof's lectures or just drop the course. His textbook is absolutely useless. Doesn't have slides, just hand writes the lecture which he doesn't even post. Couldn't care less about the students failing.

Very inspirational professor who is very passionate about teaching linear algebra however does not know how to communicate and teach it properly. Midterm average was a 49.7% and prof did not care whatsoever to curve. He replied with "In your dreams" when someone from the class asked if there would be a curve for the class.

horrible professor. horrible accent. horrible to students. don't bother coming to class, just self-study (for the in-person ppl moving forward). he's passionate about algebra and calc but that's it. all the 1/5 comments are absolutely true. that's all I can say

Even though I don't have him as prof, he's managing this course and is doing a very poor job at it (like he always does apparantly). It's bad enough that his textbook has a number of embarrassing mistakes but it's even worse when there are errors also present in the solutions of his midterm as well which caused a lot of us to fail the midterm.
