In all honestly I recommend taking a different teacher if you have issues teaching yourself. He will not go over the answers to any of the quizzes or tests unless you visit him. He teaches you the basics but then throws very difficult problems on the tests that examples and notes do poorly to explain. He's a nice guy, but not a great teacher.

The best word to describe this professor is fair. If you read the textbook, do the homework, and review the lectures, there is no way that you will do poorly. His lectures are very clear and the exams are not too challenging. He provides practice exams and the quizzes help in preparation for the exams. Homework is good to understand the concepts.

Komine turns physics into an extremely boring subject. His lectures are boring, he talks so quite that only the front row can hear him, and he didn't finish the last 25% of the course material! Most importantly, he grades exams and lab way too harshly, making it very hard to get an A. All in all, Komine shouldn't be teaching. Take Sim if you can.

Physics is a difficult subject, but Komine makes it even harder. He's soft-spoken and his vocabulary is very annoying. He says "i.e." and "admittedly" out loud constantly and it gets annoying.

Do well on your labs, study the homework for the quizzes, and practice the questions, exercises, and problems of the book to do well on exams at least 3-4 times.

An easygoing guy with very dry humor. Ask him any question, even a silly question, and expect straightforward answers. Grading is draconian but there's a curve. Yes it's a bell curve but surprisingly it helps because typically you only need 80% to get an A. Don't need to memorize equations there's an equation sheet.

Great teacher. Spends class going over the basics so you understand where the material comes from, and expects you to learn the rest yourself. If you aren't a good self-learner, this will be a problem for you, but for me it's much better than learning how to plug and chug equations.

One of the WORST teachers I've ever had in my LIFE. Study all you want for tests, you WON'T be prepared. The "review" questions he assigns to "help" you study BARELY relate to the test questions. Most of the questions are about the most random details. TONS of reading, lectures are LONG & don't teach anything in relation to homework or exams.

Class started with 30 ppl. More than half dropped after the first Exam where average grade is C and dropping. Every lectures are 1 - 1.5 hrs long Youtube Video, majority of the time is for deriving equation. In Exam, you are expected to solve a problem using only symbols and only substitute numbers at the end. Equation sheets are given.

Worse physics teacher I've ever had expects us to learn off vid of derivation then in class, you have to sit through his boring lecture and then take his tests where the highest grade is a C+ and the class average is 5/25 don't take this due he is terrible worse professor ever he should get fired completely and utterly horrible professor.

Took astronomy, no experience about physics. If you pay attention to lectures, you'll get ~90+ on essentially all tests. I studied for basically none of the tests and took notes religiously in class, class isn't finished but I currently have a 97.4%. Amazing professor, I don't understand the hate. I'm going to try to take his physics class.

while astronomy is a very interesting subject, this prof makes it not super interesting, his online video lectures are boring and don't represent what is on the tests. His tests cover things that wasn't discussed in the lectures and barely mentioned in the book. I wouldnt recommend this prof unless you have to take astr20; also tests use proctorio.

He's such a cool professor! Knows a lot! Answers everything you could throw at him, no matter how dumb the question. Do not mistake his passion and enthusiasm for the class as leniency however. He's the harshest grader I've had at IVC. Exams are very difficult as well, even if you read the text. Fought tooth and nail for a B-.

Much of the material I learned for Physics 20 was through youtube videos and cramming before tests rather than in class. The actual lectures were just three hours of reviewing a ten-question quiz on the subject and we were expected to learn the material outside of class, making the actual lectures very invaluable. Nice professor, bad structuring.

This class was a bit different than what I was used to. We did the learning as homework via online lectures and in class we would answer questions. I read the textbook instead of watching the lectures and that worked well for me. Professor Komine can answer pretty much any question you may have. Overall if you stay on track you should do well.

Professor Komine is not as bad as many of his ratings on here, he actually cares very much about how his students do & wants us to succeed. If you do all hw & assignments & get at least half correct on all tests you will pass. Hw correlates to his lectures but the tests are definitely more difficult. He is very chill the tests are just hard.

I would not take Astro again. The tests are pretty difficult and he doesn't release a study guide. You have to be familiar with the concepts. To pass the class, you need to get at least 50% on every test. You watch the lectures and read the textbook at home so you essentially teach yourself. You only show up to class to do review.

His lectures are very math and derivation heavy. This is rough for people who don't like math but really is the core of physics. If you're going into physics or engineering I would definitely recomend his class, it will still be difficultbut worth it. It will be a great way to force yourself into the math. Take a different class if you're not.

Komine grades super harshly and gives vague feedback. When asking him directly for help, I found his explanations and suggested resources unhelpful. The amount of sexual comments he made during lectures also made me uncomfortable. I dropped in the second week and got my money back. There are much better options for physics at IVC. Avoid this one.

I took this class thinking that it would be an easy way to get some credits. It is not. The only way to learn is through the textbook readings which he assigns so if you aren't fantastic at memorizing exactly all 300 pages of the textbook, you will struggle on the tests, which have very little content from the textbook on them.

There are no class lectures, you have to teach yourself all of the content through the online textbook which requires a lot of reading and memorizing. The tests are hard and don't cover big concepts, but instead little details and facts that are easy to miss in the textbook. Don't take this class if you want to be taught by a professor.

Class is incredibly hard. Tests are unpredictable and can have any material from 10 chapters of reading. No good study guides were given. No lectures either. However is an easy grader. Lots of reading and even the reading doesn't do a good job of preparing you for the test.

I took PHYS 4A about 7 years ago. This was the hardest and most work class I have ever taken. This includes all classes I took after transferring to a 4-year university and graduate school. My class had classmates who were ie: physics tutor at Kumon and another student who already had a Physics degree, and even they said the class was ridiculous

his lectures are mostly formula derivations with few examples. He'd say we don't have the math background to follow his steps and to just accept them. Tests are mostly symbols with few numbers, a VERY strict grader. Class averages were under 30%.He was the only option when the semester started, but I would've been better off not

Do not expect to pass this class even if you understand all of the course material. The teacher does not care about partial credit at all, if you get one step wrong, he will mark everything following it as incorrect. Tests are insanely difficult with insanely low averages. Ask him questions and he will show he does not care about you passing at all

This professors online astronomy class was not up to par. ExpertTA was used as the online homework system and it is absolutely awful. There was no engagement, or true learning from this system and points were deducted for simply trying. Incredibly vague and open-ended questions plagued the entire class. No lectures or PowerPoints either..

This is the professor your highschool teachers warn you about when they say "this won't fly in college." He does let you use a note card during exams but there's so much information that it's nearly impossible to remember and write it all. I did find what I learned interesting but be prepared for zero lenience. Exams were the biggest con for me.

Normally, the labs are a learning experience, however, in this class, they were more like a heavy burden that crushed me. Our class averages for the exams were insanely low, and he would not curve the exams, leaving most people in the dust. Other than that, he is a funny and caring guy who explains concepts very well. Visiting office hours is key!

The definition of a super lecturer who just yaps and expects students to learn through that. The concepts aren't broken down either. Some weird jokes about human centipede and choking that made me uncomfortable. Exam average this semester (Spring 2024) was around a 50%. No curves were given.

There are no lectures & during class you do homework together. You learn from pretty boring independent reading. Tests cover lots of material & are memorization. Topics covered could've been engaging if lectured, missed opportunity. Instead of just reading the textbook, I recommend @introductiontoastronomy on YouTube. There's videos for each lesson

The class is reading the textbook. I used the audiobook version on spotify and then looked up the concepts on youtube to actually understand them. The homework isn't too bad, but the tests are VERY tough. The study guides aren't helpful either. Tests focus on small details where the book does a poor job covering. Outsourcing learning info is a must
