if you are into RF, then you should take this class. prof was good at explaining and had many small quizes to encourage students to pay attention and keep students focused. homework was challenging, but helped to prepare for the exams. make sure you understand the concepts, because his exams are more difficult than the homework assignments.

Best professor I have had at SJSU. Knows the material and can answer just about anything on the topic. Helpful outside of class as well, will to spend the time when he can.

This man breathes and lives RF. Extremely hard tests, knows material well, goes way too fast. Insists on being fair. No freebies or brownie points here! However, he can be cool. Low partial points. Unless you are really up for a challenge. don't take him! He has no problem being cold or giving you a bad grade! Very knowledgable, genius like!

Good teacher overall. Class is not painful. He is friendly and personable but his quizes are annoying and frequent. Tests are tricky because the problems are designed to emphasize understanding. I would take him again.

seems very enthusiastic about teaching and lectures are very useful. clear on explaining concepts and about what he expects from you.

show him you willing to learn, study his lecture/Homework and sample midterm. Very nice and helpful professor. Take him.

he loves to teach, his lecture goes pretty quick. When he said he don't curve he meant it. study his homework and sample exams. Very nice guy. if you want to learn then take his class for physic 52

He really makes physics easier for you to understand. do all the homework, get a solid 10% of total grade and some problem will be given in the exam. He also gives extra credit. He doesn't curve, but his grading system is much better than curving. He is a very nice professors, very clear in lecture and makes physics interesting for you. Love his cl

Great professor except I didn't like his quizzes. Do the homework and extra credit! For the exams, all I can say is study the homework problems and the class notes. Overall, he makes you work hard if you want a good grade and you will learn a lot in his class.

He is a well-learned professor that expects discipline and intellect. Unfortunately, many student do not use their brain. That is the bottom line. Homeworks are hard. Tests are harder. He doesn't respect his office hour schedule. He is late or doesn't come at all. Slight curving is done. Study or fail. There should be more teachers like him.

BE PREPARED. I've never worked so hard in my life to get a C. AND it's lower-division Physics class! He does not really curve at all, he already pre-curved the class... (55% is a C), so be warned. I liked his style of teaching, used powerpoint slides, and uploaded his notes. Good lecturer, I just wish his tests weren't so TOUGH! Good luck!

Great teacher; If you understand what's going on, you should do fine on the tests. Grading policy prevents unhealthy competition. Do the homework!

Great teacher. Interactive method beyond regular teaching

Good teacher. Pay close attention and ask questions. He can sometimes move fast and be unclear. Hard homework and tests, but lenient grading. He prides himself on not letting you slide!

He is very good teacher,, really care about his students, his test are hard ,but he is reasonable.. Very generous in grading., n also willing to put time to the students

Interesting teacher. Always do the homework and turn them in. His tests can get tricky when concerning time dilation and length contraction. Having knowledge on the general solution for 2nd order differential equations could be helpful when dealing with wave functions (particle in a box type problems). I would recommend this professor.

One of the best teachers I have ever had. He is very invested in the future of his students. He tries to make sure that you will learn the material, and not forget it after the final. He is very focused on the practical.

If you want to learn electrodynamics WELL, this is the guy! He knows a thing or two about proper lecturing and how to make dry material interesting. He's actually in touch with the students, which is not something i can say about other 140/142 professors like Mostafavi (UGHH). His powerpoint slides are awesome! Study them before the text.

Pretty easy class, the three tests are picked word for word from a massive set of questions that he has on his Yahoo! group page, so studying is pretty easy. He also gives a ton of extra credit group pop quizzes, so pay attention and go to class.

Gives you a practical perspective, complements the text (he also works in industry). His lecture slides are great, visual. Midterms are mostly based on his lectures. Gives extra credit. Likes questions. What I didn't learn in 140 (with the other professor), I learned in 142 with this guy. Oh and he's a very cool dude.

Professor Kwok is very organized. No online HW. Lectures are clear. Lot's of examples. I love physics. I did all the hw, attended every lecture, however I managed to fail all my exams. So, prepare to not get the grade you think you will :) Over all very helpful professor. Open to discuss problems in class and in his office hours.

He's a great guy, gotta love his super clear lectures and examples. He didn't even make us buy mastering physics!

He really knows what he's talking about and his tests are really easy.

If you put time into reading the book and working on the problems the class is no problem. I really enjoyed this class and ended up with an A.

Definitely knows how to speak the language of physics. Just listen to his lectures and you'll do fine on his tests. The test problems are really easy you should have no problem with them.

GREAT GUY! He's really helpful and loves to answer all of your physics questions. Tests are also very easy!

He gives out practice tests before exams, practice them and the tests should be super easy.

Kwok has a knack of breaking down and explaining extremely difficult concepts. This really helps as 51 gets extremely hard as you get further into the class.

Very fair and easy tests!

His tests have GIGANTIC curves. I went from a C to an A!!!

What makes him a great professor is his ability to connect with students. He once sat with me for 40+ min explaining a very difficult problem. He's not here to srew anyone over but to give everyone a better understanding of physics.

I really loved and enjoyed his class last semester! I'm excited to see that he's teaching 51 this fall.

One of the best professors I've had at SJSU. I would highly recommend him to anyone.

Gives you a ton of hints when it comes to tests and quizzes. For his quizzes many times he lets people work together.

I really had a good time in his class. I hope my next physics teacher will be as good.

His lectures are crystal clear and easy to understand. This is important when it comes time to take tests.

I really enjoyed this class and had a great time with Kwok. He will work with you to get the grade that you want!

I highly recommend this teacher to anyone. He loves to teach and it shows!!!

He's very interested and absorbed into his students. He puts our interests in front of his by meeting before/after class and he's even willing to meet whenever to fit your schedule. All he cares about is that you understand the material and it definitely shows in his tests. His tests have no tricks and are all straightforward.

I really enjoyed my time in this class. He breaks down physics and makes it easy to understand.

As long as you do the homework and pay attention to lectures, there should be no problem getting an A.

This guy is a real genius! He really wants to share his love of physics to the rest of the class. Tests and quizzes are extremely reasonable with most people getting A's!

I really love this class!!! Can't wait to take more physics!

The hardest professor I've ever had. Even though a lot of people dislike him cause of the difficulty, I honestly learned a lot from his class. This is probably the best class to take if you want to learn your stuff and succeed in engineering. Would you trust a person to design your plane if they only pass by a curve? This class prevents the dummies

Definitely one of the hardest teachers to take in SJSU for Physics 50. He had high expectation from students so better read the books before go to lectures. I don't know if the homework really help because it was online and it didn't give hint. The midterm gave 4 questions and you need 50% to pass. So far, I had passing grade without final exam....

Great professor. learned a lot in class and I believe i passed this class with a B. Physics is a hard class in general. Don't blame the professor if you do not get it. those who dislike him usually are the people who don't show up for class and don't do anything. I didn't think this class was that hard, but there was some challenging parts

He is a good professor, but his tests are hard! If you think you can just pass by with few hours of study, don't take this class! YOU WILL FAIL! And btw, "Would you trust a person to design your plane if they only pass by a curve" said by Ray Kwok! so in general, this class prevent dummies from passing.

got an A in this class. I don't get why everyone keeps complaining. It's pretty easy if you based everything off the curve. I got an 81% which is an A.

If comparing Ray with other professors that teach Physics 50, he is probably the best teacher for you to learn. I swear you need to ask questions and better spend extra hours reading the textbook or watch video for understanding after the lecture. This does not mean that Ray is not good at lecturing. It is just I am slow at digesting materials

got a B. not too bad of a class. he gives a lot of additional extra credit. tests are hard but if you do your homework, classwork, and all the extra credit, you'll pretty gain about 25% added to what you should receive. I learned a lot too. by far the greatest learning experience i have ever had.

My final grade is an A-. I can't believe it. I totally work my butt off for this class. Ray is a great teacher and he puts a lot of commitment to help his students to understand physics. Take him if you want something challenging and it is the class you are actually learn seriously

Ray is a good teacher. He cares about his students' understanding of the material and is always willing to help. He even took time off work for 3 hours two days before the final to help his students out. The material is a bit confusing, but with his help in office hours, I was able to understand.

This is not an easy class !! Kwok is very helpful and knowledgeable. His slides aren't very helpful so its important to attend the lectures. His midterms are very difficult so you must be willing to spend lots of time studying physics. Have a study buddy it helps . Lots of extra credit opportunities.

*Kwok is a really good teacher, however, he does NOT teach to the level he tests.* You might be able to understand all his lecture slides and example problems but when you get to the homework you need to commit many hours over multiple days. If you can understand/complete all his hw without help then you'll easily get an A.

The most intense college class I've ever taken!! he will make you mad at physics during his exams BUT you'll understand it so well that you cannot blame him. He gives out a ridiculous curve which really all you need is a D to get a B or a B for an A. Just try hard during the exams and do all extra credit and mastering physics. ONLY CLASS YOU'LL IN.

AMAZING. LEARNED A LOT. EASY GRADER. TAKE HIM. THERE'S A HUGE CURVE!!! I FAILED ALL MY TESTS STILL GOT AN A-

Pretty cool guy. Pretty simple class. Do your work. ACTUALLY DO YOUR OWN WORK. a lot of people complain about the class but they never did the work he assigned. DO HIS MASTERING PHYSICS YOURSELF AND UNDERSTAND IT ALL YOURSELF. GUARANTEE YOU'LL GET AN A. I love this class cause I am a physics master. Gotta understand em all

Very challenging exams and he goes through the chapters too quick that you have to try to keep up, but he does try to help you understand with office hours and when he offers study sessions before exams. Overall an ok teacher.

The class was definitely difficult. I feel though, if I had tried a lot harder and had attended his office hours like other people did I would have got a much better grade. He is very help and is very responsive to emails, so there is no real reason for you to fail the class. It is very much a help yourself kind of class.

I thought I was gonna fail this entire semester. In the end I passed! his midterms are ridiculously hard. His final was okay... He offers so many extra credit assignments that it's hard to fail unless you get single digits on the tests. in the end i think it was an alright class.

Overall nice professor. I took 210 under him and he actually he gave more grades to everyone than what expected. Do not blame professor if you don not understand basic stuff in his class.

Very cool Prof.... Can easily get A if you study his lecture slides. Gives lots of partial credits.

He is very kind. If you don't understand something, you just ask him, and he will always answer you. He explains everything very well . However, if you don't work hard or you haven't learned basic math, you will be trouble.

He has his own slides which make everything so much easier! though his tests are super hard but your concepts become really clear. He's always there to explain if you don't understand anything. gives a lot of partial credit! his classes are always fun!

He is a very good professor. The best thing he taught was the complex integration that can be applied to all the Transform

Passing his 140 class requires some intensive question solving time. I'm not talking about the after class homework he's assigned, but tackling the problems listed at each chapter. If you are stuck on something, please ask him or fellow classmates. He is very helpful on explaining class materials. P.S. Being a lone wolf isn't the best idea in EE.

EE140 with Kwok is the hardest class I have ever taken as an undergraduate in EE. Prepare for long study sessions. Look over previous midterm problems, but try changing it up. You only get points for the right answer, so no partial credit. Prepare for nightmares.

amazing professor. Study the slides and you'll be all good. Quite considerate towards the students. weekly homework assignments (which definitely help you prepare for the test). Lectures, home works and slides are very much IN-SYNC!! Least C's in EE210 under him. :)

He's very considerate but can give you the trickiest papers. Make sure to go through all his slides. Grading is absolute, so he does not curve. But luckily, if you manage an 80%, you will receive that coveted A grade! Dr. Ray Kwok ABSOLUTELY LOVES his A and A+ grade students - a wee bit of partiality there, but easy-going & impartial in grading.

EE140 has the highest fail rate of any EE course at SJSU, just so you know what you're getting into. With that being said, this class is totally passable if you take it seriously. Make friends with classmates, find someone to give you old midterms, and practice the hell out of them. Exam questions always contain a curveball, so practice a ton.

Be ready for integrals and more E&M Physics content. Understand the HW and the quizzes should be good, albeit a bit nerve wracking due to time. Tests are tough but fair, but partial credit can be brutal at times. Definitely my toughest class this semester, but interesting content. Not as impossible as everyone said it would be.

I really enjoyed taking this class, but what I wasn't ready for was spending all my time on this specific class. Kwok is a great professor that truly does care about his students. I also highly encourage you take this class with a plan on a 12 unit semester. ps Ignore the salty reviews it is just filled with people who have to retake the class.

This is a very difficult class, but there are either class, TA , or Office Hour sessions every single day to help you. I showed up to every single one I could and that's why I currently have a B before the final exam grade. He is the most caring professor and the TAs are great. You can easily pass if you put in effort everyday and redo problems 3x.

I'm just going to be blunt. If you can't pass this class and instead feel like the Kwokster is the problem, you are wrong. You will have to put in more work than other typical EE classes, but Kwok gives so many opportunities to better yourself throughout the semester and genuinely cares when you ask questions. I felt like I actually learned stuff.

Professor Kwok is one of the best in the department. EE 140 is a weeder class.He tries his best to get everyone to pass. He has tutors and workshops and stays hours after class to help students. You will not do well if you don't study and go to the extra sessions. It's not a class you can pass by just sleeping on it like EE110 or other EE classes.

Kwok is one of the best in the department. 140 is a weeder class and he doesn't make it easy because, unlike other EE classes, he wants you to develop yourself as an engineer. He tries his best to get his students to pass. He has tutors and extra sessions and often stays for hours to help. You'll fail if you dont practice and go to tutor sessions.
