He is the best Prof that I have had so far. What makes him sexy is his persona

Hey he could be a good teacher if he wanted to, but he enjoys being evil giving you hard tests..also he likes to scare his students taking a lot of bulls.. about his test. I found the class easy even though he didn't like me because I got on his nerves... but I wouldn't recomend him...

I think that many students took his humor to seriously. I think he is funny. He is fast and sometimes he likes to skip, so you wonder how he got the solutions ... but in general, he is a good professor and willing to explain individually after class. His tests are harder that the finals.

I really enjoyed his class, since he made it clear. That Pre-cal is hard and all the work you put into it is reflected in you grade.

The CCNY Math dept definitely has better Math professors than him. But, he teaches well. His exams and grading policy are FAIR. Do the HW that he assigns, you will be ok. To get an A you have to BE REALLY GOOD since he takes off too many points on exams.

park zooms through the material and the only way to keep up is to do the hwk and read the next 2-3 sections written on the syllabus. his tests are difficult but if you sweat the hwks and ask him for help you will know what the tests are going to be like. anyway unless you are willing to breathe calc 5 hrs a day (yes 5hrs/day!) dun take him.

The guy is actually good and he makes students study, but the thing is through out the class u have to motivate urself,cos he goes over a few problems and all u have is the homeworks he assigns. Study your homeworks hard to pass the class, and listen to his explanations which is very helpful.

tests are hard but does a good job helping you grasp the concept of the material

Lots of material to absorb, recommend taking this class during the regular semester not the summer. Teacher is fair and generous, but stern on mistakes. good class.

Prof. Park was a great professor. By far my best CCNY math professor. If you are ready to commit yourself fully, do all his work, hw and study.... then this class is for you. If you are looking for an easy A, or a class to sleep in and still pass.... keep looking. Park is funny and keeps your attention if you give it to him.

I think he is a good professor. He explains things until you get it. He also stays after class to help you. He tells jokes in class to make it more intresting. His tests are hard, you have to know the material. It's not high school. And he also prepares you for the final really well.

Honestly hes a good guy and a good teacher. His test are difficult but if you study and work on the problems he assigns you're set He does give alot of work He does help you a lot and is willing to stay after class to help i dont agree wit those who gave him a bad rating...if you dont know the basics dont expect to pass cus he wont care

It is true that his class requires a lot of effort in order to pass. So guys, time to face the reality! Go to his class, ask wherever you dont understand, then you are good to go.

Not horrible,but not amazing. People in the class hated him but, I have seen worse; study your butt off as you would for any calculus class.

Please people this is college not high school anymore and this professor shows this to his students. You have to study for his tests since they are very hard. If you pay attention in class and practice the problems you are good. Many students complain about the way he teaches but most of the students don't realize that high school is over.

This professor is not for the faint of heart. He is a over-all difficult professor. The important thing to do is practice prior to exams and its cake. And he can take a joke so don't be afraid to talk to him normally. Work hard and his class will be easy. :D

On the first day he told all of us that we are failures and will fail his class. His negativity really did not help when in his class. I understood the material, but the tests are a different story. He gives you 1hr, for ten long questions that reqiure alot of work. Usually people generally leave out two questions worth ten points each,people fail.

park is not so hard professor, however the concepts and applications in 209 r hard, but park teaches very well, to the point, so that ppl can't get confused, exams are pretty hard but if you'll focus on his lectures, then u'll be fine.

You can study everything and still fail because his exams are so hard. The only way to pass is studying his old exams.

first, I really thought that he was arrogant but he knew how to teach calculus. His exams sucked because they were very hard but the solution is to do a lot of problems in addition to the hw and because of that I was able to finally bust out the last exam. I dont think he's bad. I grew to like him. he's the best for the calc. courses. take him!!!

I want to say that Park is perhaps one of the best calculus professors I ever had. I also thought he was a little arrogant at first, but grew to like him. He brings lightness to calculus,which is a BORING and tedious class.If you come in wanting to learn it's so much easier than defying the class and him; practice alot of probs and you'll be FINE.

Park is an interesting character. He definitely makes the class a little more lively with his fishing stories, and road trip stories, and many others. He likes to talk alot and often gets off topic, but i think his teaching style makes up for his lengthy stories. he has a unique way of teaching, he creates little tricks that help you remember thin

U know he reads these comments and makes fun of them. Take good notes, only use the text for prob and ref. But the tests to me are based on his notes. Gave me an A. But it took a lot of teeth pulling. Also don't drop out of class prematurely. He gives a redemption exam. Park I no ur reading... So WTH. Be a little nicer. God ..I need icecream.

Professor Park is truly one of the best mathematics professor at CCNY and he treats you like adults not high school immature kids. i took his class Fall 2009 and he is absolutely great professor. his exams are based on homework problems and previous exams. very easy to understand and loved his jokes. if u want to learn math 209 take prof.park

This guy he changed my life. He failed me but I learned more in his class than any other class I've taken at city. Good explanations, interesting but alot harder than other teachers. ALOT. He will violate your GPA but you'll learn alot. what do you think is more important. i got an A- next time around without having to study cuz I knew it so well

Explains things thoroughly. Considering how hard the material is and the limited amount of time you have he does a great job. He gives an exam every two weeks. Great with partial credit. The exams prepare you well for the final. Homework is not mandatory but would strongly recommend. Hes an interesting character. Your grade is entirely up to you.

At the beginning of the semester I felt like dropping because of the poor grades on the class exams. However, am happy I stuck it out because in the end I truly understood the material and aced the final. Dont quit on him his one of the better pro. at ccny

He was an awesome prof. I was having trouble early on in the semester but I went to his office and he was extremely helpful. Thanks to him, I now understand calculus much better and I got an A on the final. =)

He's a really good professor. he condenses big ideas so that you can apply just a few methods to solve a lot of problems. He doesn't spend a lot of time answering questions during class but he's more than willing after class or duringhis office hours. He makes the course tough be he really is fair. Test questions are modified either from class orhw

He is a great math professor. Just DO ALL THE HW, even if he does not collect it, it is the only way to pass his class. He teaches by doing examples. His test are fair but he does not curve. Because of him, I was able to ACE THE FINAL. If you have any questions ask after class or go to his office. Overall, he is GREAT!

the best math professor. i took his class summer 2011 and it was tough. i had no life this summer. do hw, cw, and final exam questions to prepare for his exams. he will definitely prepare you for the final. even though you may get a lower overall grade taking his course you learn a lot more. he is humorous, very entertaining class.

Your grade is strictly determined by your test grades. If you want to do well in the class then do the homework, it's all you need to do well on the exams. He's funny, engaging, and gives you a clear understanding of the material. If you're not willing to do your part then don't take his class. Really one of the best teachers I've ever had.

I'm a very hard working student but Park's class is extremely difficult for no reason. He's entertaining and he does a lot of problems but he does not teach. Some learn that way other's don't.My advice, life can be much easier if you don't take his class

Take this professor if you are serious about learning calculus. He's very concise about what you need to know and gives good tips to help remember things. He cracks a couple of jokes every so often to keep the class alive but they can get dull fast. NOTE: Is a very strict grader and can mess with your GPA. Do exactly as he says and you'll do great.

Nice guy!!! Teaches good, but a rough grader

I've always hated math but i must say he is one of the best teachers in this school. He is strict with reasons and can be entertaining in class. He is very clear about what he wants, just don't try to be too creative or "out-smart" him. He's a strict grader and exams are pretty much all the problems he goes over in class. PRACTICE !!!

I really like this professor, He's the professor that would spend his own time to make it easier to understand and his formulas are very helpful. He definitely knows his stuff and uses color markers to make it easier to visualize. He prepares you for the final from the beginning, so he isn't a easy. If you want to learn MATH take him

Very helpful professor. He explains concepts very clearly and creates simple methods to remember how to solve problems. He practices homework problems with you, and makes sure you understand the material. His tests are a bit difficult, but you can get 80-90 on his tests if you do some the homework. Lessons are quick, so don't skip class.

loved this professor. :) he is strict with attendance.

He is a tough cookie and it's his way or the highway.I love his way of teaching because he's the only professor who takes time to use different colors to teach. He also makes math SO easy when he explains. I got an A+ in his class & the tip is DO THE HOMEWORK & do as he says. Practice makes perfection. Pay attention to the problems he does in class

he has 5 exams and one final. Drops one of them and makes everything understand clearly. Fun to deal with. Cal 2 is basically hard so studying will make it easy. He is not that easy, but studying will keep it balanced.

Absolutely best math professor you can have. VERY organised, provides with detailed notes for each and every chapter. Discusses all the topics in class and prepares you for the final from the very beginning. Good luck!

I am cursed when it comes to mathematics but I could not thank Mr. Park enough for making sure I understood each and every concept on his syllabus. Aside from the classroom setting, he is a compassionate and well-rounded individual with a peculiar sense of humor that one could come to appreciate. Thank you for letting me graduate on time :)

Park is THE MAN. His tests are extraordinarily hard, but the final was a breeze. Do not skip class. Study and You'll do great. If you can get old exams study those.

Pay attention in class and you will be fine. 5 class exams, 5 computer assignments and a final. Most of his exam questions came from textbook with a few alteration. Other than that, there was no homework. He would sometimes make weird jokes and a bit touchy.

Park is a great professor. If you study and do homework you'll be fine. Expect off base jokes and some picking on certain students though.

Prof. Park can be a bit intimidating in the beginning but he becomes a little more approachable as time passes. His lectures and notes are amazing. I've barely had to use the book to understand concepts since he explained them so well. The tests are tough but they prepared me extremely well for the final and I was able to finish it with ease.

OMG, GREAT TEACHER. I honestly loved this class. He was a very clear with his teachings. Funny too, very funny. He keeps you posted on how your doing throughout the semester, so you always know your standing. Do the work he assigns on the syllabus, although its optional, IT HELPS! Tough test grader but he gives extra credit! Take him!

First day of classes he's very intimidating. But as the course goes along everyone gets comfortable. He's funny but also very serious about your work. He has 5 exams and a final, lowest grade dropped, DOES NOT CURVE. Optional HW, but you should do it, really helps with tests. He also has problems online! I did them all . Take if you want to learn!

Prof Park is that dude. Hilarious and a good guy. Don't have to be in class, but you're asking for it if you don't go, he teaches some topics differently from the book. Tough for me because I didn't study enough till the final so I only go a C+ (totally on me), but if you DO STUDY assigned HW, they'll come up in exams and on the final very similar.

Park teaches math his way. He want everyone to follow his procedure. You will only pass the class if you follow what he says. COPY EVERYTHING ON THE BOARD. His tests come from the examples he gives in class directly. He also enjoys talking which is pretty annoying but can't be helped.

Sure, Prof. Park is a harsh grader and his tests are on the challenging side, but as long as you do the homework (very important) and ask questions whenever you don't understand something, you will do just fine in his class.

Park teaches really well and you're almost def. gonna understand the material he teaches but his tests are still extremely hard and he's really harsh at grading them. Def. do ALL the practice problems he gives you on the syllabus. He gives a lot of extra. review material that is really helpful but again, it's still hard. Go to office hours he helps

Park was a good professor, he provided very good notes online. And if you do the homework, you would know what was going to be the exams. I would like to take him again.

Park does not curve; his tests are harder than other professors. HOWEVER, his in-class examples and ONLINE additional examples are the most helpful I have ever had in a math class, and I suck at math. Do ALL optional hw with his notes and you will do fine. Gives decent partial credit on tests. Take for learning how to solve problems, not for an A.

Professor Park is very helpful. He knows the material inside and out and he explains thoroughly. If you dont understand something ask him he will go over it but if its a silly question expect a little humor. He is definitely a hard grader but only because he wants you to succeed. Dont miss class if you have a hard time learning from the book.

Park is a really tough professor for calc 2. I was told to drop him and take somebody else but I still took him and I liked him. He actually teaches good and knows what he is talking about. If you are serious about math, then he is a good choice. His homework problems help a lot and also the examples he has online. Do the homework problems!

Awesome instructor! He really enjoys teaching so you will learn a lot. Like every other math class you don't want to miss class. Exams are really easy if you do all the suggested problems, HW problems, and attend class. Every exam had problems that he used as an example in class or in the hw. He's sarcastic and that's what makes the class fun!

Amazing professor, very straight forward, teaches you what you need to know for his tests, he gives you 5 tests, which is awesome since you have a chance to bring your grade up, and because there no more than 2-3 chapters per exam to study. He may be sassy, but his teaching style is great.

Took him for 209 he teaches pretty well and is real with the class. EZ class if you got the pass tests. Otherwise its hard af.

Look, this isn't an easy class at all for those who don't like math. i LOVE Parks. He cuts the BS and teaches hardcore. Do the homework assignments and thats IT. So many negative comments for no reason. Yes, he's rude at times but he makes it up with his teaching.

Prof. Park is great. Calc 2 is difficult, so you really have to study, practice problems are key. Lectures were helpful and he is always willing to answer questions and help. Exams are difficult but they prepare you for the final. In addition he provides study guides that are useful. Overall if you want to do well, you have to work for it.

Also a word of advise, try to do really well on the first three exams. The topics get progressively harder, especially test #5. He does drop the lowest exam, so save it for the most difficult topics!

I'm taking him right now and I honestly really enjoy his class. He says we have 5 exams not including the final and the lowest gets dropped. Very lecture heavy and it's crucial that you pay attention and take good notes, do that and you'll be fine. He is hilarious (in a corny way) and he curses A LOT. It isn't for everyone, choose wisely.

Took him for a summer calc 2 class. A lot to cover in very little time, but an excellent professor. Lectures were very helpful. If you do take his summer class and are aiming an A, then you'll have to work a lot outside of class (2 to 6 hours a day), but he really does the most he can in class. An excellent choice for fall/spring classes

Park is an amazing professor. He doesn't make the class so much about just the lecture, he provides help for the tests and keeps it real. He also has corny jokes but it helps to lighten up the stress of the class. Make sure to do his homework even though only the test is graded. The homework questions are almost exactly the same to test questions.

Listen that class was hard once you get to chapter 10 up. He is an amazing teacher but if you don't try you won't pass. he gives pass very few students and gives A's to even fewer. If you think you can work hard and actually put effort you will be fine.

Great professor! His tests are a breeze as long as you do the homework and study. Grade is based on the in class exams (5) and he drops the lowest one. He gives great tips and tricks on how to make the math easier and is explains well. Straight to the point in teaching, with complimentary dry jokes on the side lol. Don't listen to the rumors.

An amazing professor, who simplifies the content and teaches only what is needed. He is also one of the most realest professors I've met and has a great sense of humor. You need to put in the work to do well, like the rest of the math classes.

Ive received B- and C+ on my all my math courses from Math 190-Calc 205. I reached Parks and he was the only professor available. I started doing all the homework's and wow can this man teach. Hes hilarious and really does not care if he offends you. Hes a great person though and you will FOR SURE learn and keep it for long term. Ty Park.

Fall '19. Structure was 4 exams, 60% of grade. Final 40%, 5% Extra credit. Tough class and Park makes it even harder. Don't slack off or you'll probably fail the class, the exams are based off textbook but you need to study hard for it. He said he doesn't drop any exams but at the end of the semester he dropped one. Good teacher, hard exams.

Exams (four total) are 50%, the final is 40%, and excel homework is 10% of your grade. He gives homework questions (for you to practice). My recommendation, DO THE HOMEWORK PROBLEMS! They are similar to his exams and you will pass and understand the material better. He tells jokes a lot, so be ready. He does not give extra credit, so do not ask.

Amazing math professor. Teaching style is really different than others. His exams are NOT difficult. IF AND ONLY IF. You do the textbook questions, ALL OF THEM. Understand that and you will excel (homework too) in class. I have received B- on all of my math courses, it is not my subject. But did great with Park. Keep teaching park. Thank you!

This course is hard, so are the exams, however professor park does his best to teach the subject. He challenges you to learn the material. Yes, the transition to online class was hard fro him but he still taught the material well. Exams are hard, but he's also great at teaching.

Overall a hard course, however professor park is the best professor for math209 because he knows how to teach the material. This course is exclusive to CCNY and different from most courses, and professor park knows how to teach this course well. The exams are hard though.

Due to Covid-19 the course became a little more difficult after it was moved online. He made the final worth 65% but I think he did a major curve in the end because I don't know how I got a B- but I'm grateful. His exams are very difficult and he only gives an hour to do it. I could say that I learned a lot with him though. He's a interesting guy.

He may be a jerk but he sure cares for the students that want to pass.

He knows what he's doing. However, you need to read the textbook chapter before class so you are not entirely confused during lecture. Sometimes he moves quickly. He also expects you to be able to answer his questions, such as what to do next. There was not a lot of hw. We had computer assignments on excel. Lectures were recorded.

Best math professor I've ever had. He really knows how to explain the concepts. Uses a great deal of profanity. He will literally put questions from the textbook on the exams (won't even change the numbers, often) so make sure you practice those to do well on the exams! If you skip lecture you're doomed. Go to tutoring if you're confused.

He was actually funny, just be nice to him and he will 100% be nice back.

He teaches well and explains things clearly. There are no pop quizzes but there will be a webassign quiz at the beginning of every class, which is normal. The questions are really easy and there are only 2-3 questions. Just pay attention and you'll do good in this class.

The only reason I withdrew is because i changed my major and 209 wasn't required but LOVE THIS MAN. he's the best. best math teacher, i dont care what anyone else says. Hes tough and he moves fast, but if u sit there and pay attention, its literally fun, and I hate math. Hes funny as hell too. Tests are not curveballs, its what you do in class!

Prepared the class well for the final, and provided many tutoring sessions. Gave us plenty of material throughout the course. His midterms are always variations of questions from the book. His grading criteria are just the 3 midterms and a final. Overall great professor, he provided all the material for the class and prepared us well for the final

It is a math course so be prepared to study and work hard. He takes attendance every class and if you miss a lecture you will be behind. Overall a really good professor and gave us the material we need to pass

Professor Chun is tough but fair. Attend class, use the free textbook, and practice the problems - you'll do well. Unstuckstudy was a game-changer for me in this course.

Technically attendance not mandatory but you're flat not going pass if you don't attend and learn how to solve the problems. Material itself is a Lot in a very short time but he's very good at explaining. Very accessible outside and after class. Also tells you exactly which questions will be on exams which is great

205 is a pretty easy class when compared with 201 but if you're not on top things, you will fall behind. He has a clear grading criteria and there's no homework. And most of his tests and work seems to be well thought out. For example, most of his problems never end up having some crazy solutions but they simplify down to a simple answer.

The class is relatively easy just you need to attend lectures or you will fall behind. There is HW on Excel and exams which are reflective of problems done in class. He makes material easy to understand if you don't pay attention you just asking to fail or get a bad grade. He's fair

Put in the work and take the initiative. Grab algebra by the you-know-what and you'll be fine. He yells sometimes, which can seem off-putting, but it's nothing personal. Do the workbook and textbook problems and always ask questions! He cared students did well and even went out of his way to give us example questions that he would solve. Solid.
