buy both the solution manual and the book,it will help you get the hw. he assigns a fair number of hw problems. his tests are short (12 problems, gives lots of time to complete tests), show as much work as you can on tests so he can give you partial credit. concepts are easy once you get them. he gives you credit for hw just for doing it. easy B.

the subject itself is easy; high school math if you ask me. easy class, do the homework and study for the quizzes and tests. sometimes he lets you use your notes during tests which is VERY helpful. a lot of the quizzes and homework problems are on the tests. easy A/B!

Easy, Easy, Easy

Great teacher! you work for your grade but overall his lectures were clear and his expectations of the class are clear. I failed this class in high school and took it again for kicks and I came out loving trig! Ninh is strict as far as talking but learn to raise your hand to ask questions instead of asking a neighbor.

He's really not a hard teacher. Do the homework and ask questions if you don't understand something (he'll keep going over things until you understand). Some of the test/ quiz problems are directly from the homework. The people that are leaving bad reviews sound like whiners that don't do their homework or just copy it from each other.

Whoever left the review on 11/10/09, I have to agree. Despite what all the other reviews say, he tries his best to make sure you really understand the material. My one complaint happens to go along with that - he'll spend the entire class period doing one problem just to make sure we get it. However, because of things like this, we're way behind.

I took Pre-calculus class with him for the fall 2009 semester, and it was great! His quizzes are so easy, and if you attend class everyday and do well with those quizzes. His tests were like mid-hard, but just like many people are saying here, if you do the homework problems, you will do fine. If you as a question, he can most-surely answer it. The

Professor Ninh explains concepts extremely well and can help you understand basically anything subject-related. On the downside, he does too many examples of easy material and falls behind schedule. Nice guy, but Tests are difficult!

He maybe boring but he tries his best to help people out. He doesn't mind staying after class to help students out even though it might take more than an hour. Attend to the class everyday, do your hw and ask everything you don't know then you get an A. i learned a lot from him

Mr.Ninh is a really helpful teacher! I can see why the people who rated him as a poor teacher...and sadly...that's because they are either **** or slackers!! He always offers help and kindly repeats steps (if needed). You should definitely take his class!

Mr. Ninh is the best math teacher I have ever had. I got 100% on every single quiz and got an A on every test. He makes it very easy to understand. He doesn't require a book during class you just need it for homework. The most homework he gave per section was 20 problems.

What? There has to be two Joseph Ninhs at this school or something. This guy is an amazing professor. Very clear lectures, and always available for help if you don't understand something (hardly anybody needed extra help, though). Very fair amount of homework, 10 minutes to 1 1/2 hours per night. Wish he taught higher level math.

AMAZING TEACHER!!,take him,do the assignments,trust him,ask him if u have questions,u'll get the A!

I thought he was a very good professor. I ended up with a B because I took another class in the Summer along with Math and was working full time, so I had to split the studying time. With a little more time, definitely would get an A. I would recommend him as a professor. His test are really based from the HW and the lecture problems.

He's an average teacher, which is why there are so many varied comments about him. he's really not that bad of a teacher, but you do have to put forth a little bit of extra effort to understand exactly what he's trying to say. When you get used to his personality and his accent, he's not a bad teacher.

You must work hard if you want to do well on his tests, especially in precalc. Homework is worth points and attendance is mandatory. Very precise about what he wants you to do. Very intelligent guy, but his tests are killer.

amazing professor! passionate about math! goes step by step for each math problem, able to work with you after class. too bad we couldn't learn more b/c we had horrible annoying immature classmates! he's a fair professor. all the other comments were probably trouble-makers. if you have questions, always ASK!

A helpful and good teacher.This is my first Math class after I left school for more than 20 years,and I managed to keep up and get an A.Quit complaining, do your work, ask for help and you will do well:)

Im currently taking his summer class. Its fast paced and although this Is a repeat course for me he actually takes the time out to make sure everyone understands each section before moving on. HW is a must in order to expect a good grade. He is very lenient on curving the tests if needed. I highly recommend taking him.

I would take him again.

He lectures for the full time allotted and always assigns homework. He tells you what will be on the test but he does grade fairly hard. Expects you to completely simplify answers which can be difficult at times. He answers all questions and generally seems pretty excited to teach calculus O_o Don't skip lecture or you will have to teach yourself

Ninh is a great math professor. He answers students' questions in detail, takes time to go over homework questions, and his lectures are clear and concise. He assigns a lot of hw but it is necessary to understand the material. He tells you what is exactly on the tests. He can be a tough grader- you have to show all the work carefully.

Dont believe what the others say. This is a good professor. He really cares about his students and teaching, however he is a tough grader. If you do the homework he assigns, you'll be fine on the tests. Would definitely take again.

Ninh is nice. 3 quiz, 3 exams and 1 final. You need to know, that other professors need quiz every week, and exam every 2 week. I believe other students who give him bad feedbacks cuz they don't do homework but expect an A.

His test is based on homework + problems he went over in the lecture. He start the class with helping students with hw questions, and he answers questions step by step. However if students ask a lot of hw problems, then it delays the lecture, which leads to more class time than usual Quiz+test are really easy if you know what you are doing

the best math professor on the earth, reasonable questions same level of his teaching not like others who they give exams higher than his teaching level at Irvine valley college

I thought I can get an A at the beginning, but a B. The reason is that: first, he is a tough grader. second: the text of the final is different to 3 exams. I mean he use his own words to test you on the final. But cuz I'm not a native and he is not a native either, so it is hard to understand his question. Continue..

Continue When you are taking a final exam, but strange sentences that you didn't read before. Definetely, you will be nervous right? Not only me, but my friend who took his 3B. Before final exam :B After final exam: C So be cautious, especially 3B students.

he deserves more credit and praise than he actually gets, so great teacher and great man too. enough said.

Inspiring, encouraging, and most important of all. AMAZING!

Extremely intelligent and helpful. I definitely recommend taking him. Give you homework so you can earn small amounts of points. Quizes and tests based on homework so make sure you're in class to understand the lesson and do the homework so you know how to do it.

He is such a great professor

Very good teacher. Lectures are clear and organized, does not rush through examples. Homework and quizzes so your grade is not dependent solely on tests. Tests are on the harder side but if you study and do all the homework you'll be able to handle it.

He truly enjoy teaching. I took 3 A and 3 B with him, both B. You will think he is easy if you only take 3 A with him, but when you are turning to 3 B with him, he will not tell you what kind of questions will be on the exam. Be careful.

Professor Ninh is a great professor. Although his class is straight lecture, he does teach very well. He takes his time teaching us and makes sure we understand the material. He is a little akward but that's a big thing i like about him, it's a funny awkward. FYI: NO PHONES or he will kick you out. Overall he is a great teacher.

It's Calculus, so if you expect to get an easy A, it's not happening unless you're naturally gifted. Ninh's class isn't that hard though; he's clear during lecture, helps with homework problems, takes his time to explain difficult concepts, and assigns homework that tests are based on. He's a nice professor that's good at teaching. Take him for 3A.

I've taken calculus more times than I'd like to share but this is the first time the material has made semi-sense to me. Ninh is great; he explains the concepts well and his tests/quizzes are heavily based on class notes & HW. Make sure you are coming in with a strong trig/algebra foundation; this is crucial to the whole course. Be ready to WORK.

One of the better math professors I have had. If you really want to learn the subject and truly understand the material, Ninh will help extensively in this. His tests are not the easiest questions and unless Calculus comes very easy to you, doing the homework questions to get all the variants is a good idea. Partial credit is tough to get.

Even though he kicked me out of class once because I was cracking awesome jokes with my friend, professor Ninh is not that bad of a teacher. I love Calculus and he taught it well. He provides more than enough information for the Exams. He takes the time to go over homework. The poor rates are students who probably shouldn't be majoring in Math.

The class was pretty hard but that's expected with almost any math class. Professor Ninh is a very hard grader but is very detailed in his lectures. He does not really seem to care about growing relationships with student, but just teaching you what needs to be taught. Not that big of a personality, I would take it if you take mathematics seriously

His exams and quizzes are directly to his lecture notes. He never put a question that he didn't talk about in lecture. However there are lots of homework to do. In fact if you finish all his homework, all test questions are included. You don't need to review other problems.

He is one of the best math professors. Exams are really similar to the homework he assigned to you. if you understand the exercises and solve the problem the way he teaches, you'll get an A easily.

I like Professor Ninh because he is very energetic (keeps your attention!) and it is easy to tell he has a passion for math. At the beginning of class, he would take time to go over homework problems assigned from the previous day. His tests consisted of 4/5? quizzes and 3 exams. He would also take time to review concepts the day before each exam.

I took his class last spring semester, and I believe that he is a nice professor. He tries to answer every question during his class, and most of his quiz and exam questions are based on his homework. If you want to get an A, and if you can spend some time on his homework, it will be not that hard to achieve it in his class.

Professor Ninh is a very caring professor. He takes the time to explain any questions you could have and details everything out meticulously. His tests and quizzes are curved if the class doesn't do well. Our exams were curved 0%, 5%, and 7%. The final exam was cumulative and very challenging. All other quizzes and exams were really straightforward

Great professor. His lectures are easy to understand and the problems on the test are very similar to the ones on the lecture and homework. Tests are curved and one lowest quiz is dropped. Review lecture notes and homework problems and you will do fine.

Professor Ninh is the best. This was my second time taking his class. I had him for 3A too. His lectures are really easy. He takes something so complicated and breaks it down clearly so you can absorb everything and you don't have to go home and teach yourself. Exam questions are based on the examples in class so study those and you're set.

Calculus in general is very hard and if you expect an easy A, youre not going to get it. You need to put in the work and have a STRONG pre calc background. Prof Ninh is a fairly hard teacher but you need to spend a lot of time on homework and pay attention in class. The final was impossible. Tests are 45% of the grade (3 tests). YOU NEEED TO STUDY

Professor Ninh is great at teaching and will help you whenever you need it. I took his summer class which was relatively fast-paced but it is very doable. As long as you do the homework you should do well on the tests.

Hard class. Good Professor. Hard Tests. WebAssign Homework(Free Points). 3Midterms, 1 Final, no Quiz. NO or Little Accent. Live Lecture and Recorded. No Curve. No Extra Credit. Tough/fine Grader. Helpful in Class, not much reachable in Email. No Proctorio Test.

I got an A in his MATH3A class so I decided to take him again. Lectures are mandatory and he takes up the full 2 hours. A lot of homework and his tests can be difficult but if you do the homework right after lecture and don't procrastinate you will be fine. The exam problems are problems he goes over during lecture. Overall a good prof!

Calc 2 is hard, it has lots of tedious problems/easy to make mistakes. Must memorize trig identities/derivatives/antiderivatives. If not memorized you will struggle to finish exams on time. It will take a lot of practice and time. He only put questions on the exams that we went over in class or hw which I appreciate, he also gives partial credit.

Many of these reviews make him sound worse than he is. If you go to class and take notes, you'll easily get at least a B. Tests are based on HW questions, don't procrastinate, and go to office hours for questions. He knows how to teach well and gives many examples for every concept. He is kind, passionate about math, and wants to see you do good!

This class was great. I feel he covered everything so quickly. His notes and lectures are so clear and he assigns a lot of homework but it will leave you ready for the test. Very effective professor for a difficult course.

I have taken 3 math classes now with Professor Ninh. Trigonometry, Pre-Calc, and now Calc 1. Professor Ninh is a great teacher. Take thorough notes, give a solid attempt to every homework question, and if you get stuck make sure to ask for help. He gives every tool for students to succeed in class, but you need to put in the work and ask questions.

What is everyone talking about? Professor Ninh is an amazing professor. During his lectures, he breaks down complex topics into digestible pieces. Yes, he might give a lot of homework, but it really prepares you for the exams. He'll even ask you if you need help with it. He might not openly show it, but he cares about you and wants you to succeed.
