Actually you just do the homework, and you get what he is doing. He gives a lot of extra edit, suppose to be easy to get As , just that he often dis you with his attitude. And he usually give a really hard test at the first time, which is the first exam.

He is okay~ Just that he always acting so excited , you don't know what he'll do next , very weird guy~ but he is nice , he just like to talk about how hard he is~ bascially just do the homework , and really learn for urself~ don't rely on him too much.

do the HW and pass, otherwise don't bother to show. tests are hard! doesn't eplain much in class.. from a class of 55 went to a class of 6 in two weeks.

I think his teaching is very clear. I could understand what he's saying.

pretty easy and clear

he is easy because he gives a lot of extra credit:) you will actually learn (if you go to his class). a really good teacher!

I wouldn't say his class is easy. However there is extra credit. Kinda boring though.

I had an A in his class but that's because it's my favorite subject and I worked my butt off for it! He's not easy but he's not a bad teacher either, so take him if you're good at math or are willing to learn.

Get a grip on life; He is paid to teach not to care about his students feelings. I liked him and his teaching style. Very professional not feely-tochy.

I like'm. I did the homework and had no problem. He helps only those wh don't waste his time with stupid question.

You will get very high scores, together with extra credits, in mini-tests and exams if only you study the text extraordinarily hard. "NO BEACH in this summer~~" :)

Very good if you study hard. Easy tests.

Awsome teacher. He does not waste class time with the bozos. He is not one of the bleeding hearts that will pass you for just trying. Expects you to be prepared otherwise he want bother with you. Easy tests if you paid attention in class.

Good lord, what's up with these ratings people? He's the easiest math teacher I've EVER had in my life. Period. Pay attention in class, work all the problems, attempt everything, don't be shy in class and there's NO WAY, I guarantee, NO WAY you can get lower than a B in the class. His midterms and exams are EASY if you do the necessary work.

quizes all from text book reviews, do the extra credits.very clear on lectures...

Mr. Klein is an awesome teacher. Like any self-respecting Mat-Sci teacher he does not subscribe to that “self-esteem” crap. So study hard and keep notes and you’ll have an easy “A”. Calculus is not for morons.

I'm interested in attending his 49b class, and he teaches very well.

I like his way of teaching. if you study(read book, take notes, do the hw), you will definitely get an easy B. grading is fair, and you can actually learn something. just don't be lazy and go to class, you will be fine.

Although he might have jazz hands, he is an excellent teacher who can help you out if your in need. He gives extra credit questions in exams as well as he doesn't check homework. If you have done AP AB or BC, then this class will be a piece of cake. At some point he gets excited, but all in all, he is a good teacher.

I've taken him 3 times and I really enjoyed his lectures. He explained the concepts very well instead of just showing how to do problems. His exams are pretty tough and he almost always includes one problem that is hard and requires you "think outside the box" and understand the concept really well. I feel that I'm better at math because of him.

He is very good math instructor, his lecture is very clear. He puts every quizz and exam one problem for extra credit. As long as you understand the concepts and do enough homeword exercises, you will be doing great!

He is really good teacher!!!!!! He doesn't check homework, but you have to do it to catch up. I hate math, but I really like his lecture, I am never bored!

Very helpful teacher. I like his lecture which is clear and fun. Although I don't like math at all but I love to come to his class. If you do the hw and come to class, the tests are not big deal. A lot of test questions came from your hw in the textbook. Lots of x-tra points in the tests.

He's a nice guy and teaches well but the problem is his tests are really hard. Even if you go to the lectures and do the homework, the tests are still really difficult. If he was gonna tests us so hard, then the hw should be the same that way we have an idea. Tests weekly. Doesn't collect hw or keep attendance. I guess that's the only positive.

Even though I got an A in his class, I still think he is pretty damn hard. I got an F on the first test but I studied really hard afterwards and made it. If ou want to do well, you have to do all the problems in the book :/

Has 'little-man' complex--is more interested in making you conform to what he says than learning the calculus. Has 7 exams and a multi-choice final. Uses "mini-tests" instead of quizzes, but they're full-blown exams with less time to do them. Lectures are clear, but he falls behind and drops entire sections needed for later classes. Awful prof.

Very interesting and helpful teacher.He makes math become vivid and funny. The tests are pretty hard and he requires us highly, but he gives us lots of assignments for extra credit.If you really want to study math, take his class.

In a word, Mr. Klein is lively. His lectures are interesting because he speaks clearly and expressively, and keeps the class involved. Some might say he's a picky grader, but I find that his requirements are sensible. He always gives an extra credit problem on tests, which makes it easy to do well regardless.

I find this teacher to be very good. As usual, must do the homework to do well in the class. Dynamic teacher who keeps the class involved. Tests are fair, even if long. Offers some extra credit but would count on it to improved grade. He hands the tests/quizes back the next day and goes over them. It really is a learning experience.

i took his math 1c and it's extremely easy. i always escaped his classes...but i still got an A. the final is very very easy.u always have extra credit on every exam quiz and final. very good easy teacher. highly recommended

Mr. Klein is a realist, he's funny and will explain anything you don't understand; although he might not go over it very long-that's when you go to his office. The homework is not mandatory, but it can be helpful because he uses problems from the homework for his 'mini-tests', and extra credit is always given on the exams and mini-tests. :D

Fair teacher. He offers a lot of extra credits on "mini-test" and exams. He enforces his green sheet strictly and stresses the importance of reading it thoroughly, which include no make-up "mini-test". His lectures are clear but sometimes relates math with real life, which sometimes throws off my chain of thought. He goes over homework in class ONLY IF you ask him.

took him for 2 courses. I took 1D last q and I thought he was very boring and his test were just so-so and I never finished all of the questions in the test. However, I now take Math11 and think he is a funny person. good lecturer but not that good. fair test as long you do the HW. lots of ExtraCred

Klien is easy to understand, but your grade is only based on the exams and quiz scores. I attended every class and did extra credit. I did all the homework and studyed. I recived a D in the class. Klien's tests are multiple levels above his lectures. Re-took w/different teacher and got an A. Klein is not worth your time and money.

I started math 1D w/ mosh- I switched to klein after just one lecture. much better teacher. U can actually understand things. tests are doable. there's always an extra credit problem worth as many points as other problems. So if you don't know how to do one problem, fine,just skip it, do the other ones. very good professor that prepares u well

Don't understand why people say hez hard. His lectures are pretty clear and quizzes are really straight forward. Ok tests are a bit harder but still doable if you know the material. No mandatory HW &attendance, great for student who prefer self study. Lots of extra credit.To tell the truth, I didn't do even half of his assigned hw and still get A..

ok, first of all, this is a MATH teacher. a lot of ppl find math hard so quit blaming the teacher!! I think he is a good teacher that actually cares about you learning the material and not just passing the class. I like being challenged and actually earning my grades. So if you are dedicated and actually want to learn, take him =)

Mr. Klein is very animated, loud, and easy to understand and focuses on your notation. He has no tolerance if you screw up on your basics, and he can be quite hypocritical in what he teaches: ie, it's okay for him to screw up his notation in lecture, but not the student. Leaves very condescending remarks when he grades your exam. No partial credit.

Fair grader when i first entered his class almost everyone failed the first quiz and didn't do that great on the first chapter exam. but if you stick around and attempt to understand the concept, you should do fine. lots of XC on tests but time is limited. tests can be a little difficult at times but doable. not easy A class. recommend if u <3 math

Klein is an animated teacher. He got really excited about stuff that seemed easy, leading me to believe that I would do fine. But the tests were tough. I started doing my homework and pulled through with a B.

i am taking his class now and i think he understands the material very much so his lecture is pretty clear. Although his test is not easy and i did not do pretty gd in that, i still learn a lot of stuff in his class. So, if u want an A, dun take him unless u r genius. But if u wanna understand calculus, he is definitely one of ur choices!

Professor Klein is very intelligent and he is a hard grader. He emphasizes student should have good skill of algebra. His mid term is not very hard but Time is limited there are a lot of XC in the test even in the Final exam. Final exam is only the MC.If you do not have good algebra, i think you should not take him.You can learn a lot in his class.

First let me say that math is my absolute worst subject. Mr Klein truly understands his subject so his lectures r crystalclear However he holds high standards of work quality, so prepare to do the work and do it right! He is fair and there is lots of opportunity for extra credit. 4 exams, 3 mini tests, 1 MC cumulative final. hw/attdce optional

I don't know what other people are talking about. He's class in not easy, but if you keep up with the reading and pay attention in class and actually "DO YOUR HW", everyone should have no problem getting an A in his class. He's quite hyper sometimes, but cool, awesome professor.

I'm really annoyed with people bashing teachers on here. Professor Klein is a great teacher. He expects his students to be responsible and STUDY. If you are serious about learning math, and are willing to do the work he will help you get there. Don't say it was hard if you didn't study... I'll be taking him again next qtr :) He knows his stuff.

His lectures are actually good, but his tests are hard. He doesn't give you enough time to finish it and most of the questions are not based on lecture/book/homework. He even said that his tests are designed for you to skip 2-3 problems, which are 20-30%! If you're not a natural at math, don't take him. ABSOLUTELY NOT FOR SLACKERS.

It is true that he is clear on the lectures. His exam questions are not hard too, but it is just too much work. I got all the answer right, but if you are not doing the way he expects, you will lose half of the points. If you want to learn, take him. But if you want an easy A, stay away from him.

Many Students think his class is too hard. Actually I think his lectures are interesting and clear. Besides, he will drop your lowest exam grade, and provide some extra credit opportunities in every exam. But if you want to get an A in this class, you really need to work hard out of class.

I've taken this course once before but dropped it because the professor wasn't clear and made the material seem more difficult than it really was. Klein's lectures are CLEAR. Minitests and exams are straight to the point and not tricky. He replaces your lowest test grade if you do better on the final and gives many extra credit opportunites.

As long as you do the homework, you should be able to get a B or higher in the class. He gives take-home tests sometimes and they are a lifesaver. Exams are not hard, but you are rushed. You have to average a problem ever 5 minutes. He gives an opportunity to get an extra 10% on EVERY exam, though.

His lectures are very clear and interesting. He always gives an opportunity for extra credit every test/exam. The class is hard, but if you do homework you'll be fine. I highly recommend him.

I have taken a lot of math instructors and i think he is a great instructor you just have to really work outside of class. If you attend class daily and do your homework there is no reason to get a grade lower than a B. He likes to throw a few curve balls on the tests but if you really understand the concept you should be good. Study, Study, Study!

Grade is 100% based on tests. No attendance required, leave or show up whenever. Previous math classes let you slide if you got your point across by answer; this class is like a math class and a language of mathematics class combined where you have to use proper syntax to present your work and answers. At least he was helpful after class.

Professor Klein is engaged and cares deeply about the subject and his students. Although he is critical when grading your work, this is only to improve your skill set. Lectures are broken down and explained throughly. In class there is a healthy environment where students are encouraged to participate. Highly recommend.

I find his classes helping in 'laying foundations in my trigonometry skills.' However, he indeed is a tough grader as others say, and tests are difficult; some of the questions you've never learned in classes. In tests, he emphasizes format and presentation. If you make a tiny error in your presentation, your points will be deducted.

Klein is very picky with his grading. The tests, quizzes, and labs are very hard to do well on because he will inspect the paper with a fine-tooth comb for issues. That being said he makes up for this with a very generous grading policy and is willing to help students with things that aren't clear.

He's been criticized by many, which made me confused. He's very sympathetic. If you ask questions about any other than Math, he responces every single question. I've been doing simple things. I read textbook before class, and try to understand what he says, and never leave questions unsolved. He's generous to who are zealous. 4 letters' word: READ.

Not sure if past reviews were written by bitter students who didn't do so well due to lack of studying, but Klein is a wonderful statistics professor. He's very passionate and his lectures are never dull. Statistics itself is tough, but if you study and put time into learning the language, you'll recognize everything on this tests and do well.

I was scared to take stats, but he made it pretty fun and interesting. If you want to do well, I recommend attending all his lectures and reading the book. He offers a generous amount of extra credit, which helped me out a lot. Lowest exam, quiz, and lab are dropped. GREAT PROFESSOR, TAKE HIM!!!

very caring and good professor. He's there for you if you ever need help and encourages you to think. Attend class because it helps a lot with studying! I would take him again because he's a good lecturer. If you read, attend lecture, and ask for help, then stats is easy peasy.

I honestly dont know why he's getting such bad scores. He's a tough grader, and if you're bad at math, you can still make it. You just have to study hard. Do a lot of textbook problems. IDK why people say he lies about getting problems out of textbooks, I don't think he lies about that and even though exams are hard they are still similar problems.

Great teacher, very clear in transferring the material from his brain to yours, lots of homework but nothing impossible, homework not mandatory but it is strongly recommended if you want the tests and quizzes to be a breeze. 10/10 def would recommend best math teacher i've had in 16 years

I honestly dont know why people said hes tough. Yes his materials aint easy to understand but he is kind and the tests are easy. He doesnt require attendance and always gives extra credit on the tests. Moreover you only need 88% to get an A on his class. Id definitely take his class again if he ever teaches 1B tbh
