Overall, this class was a pretty good class and Professor Ong explains most concepts pretty well. I think for this class it is really important that you read the textbook. He likes to pull a lot of his test questions from the readings in the textbook and I'd like to say that some of his midterms + finals are really just fun-fact questions (for the conceptual questions especially) so it was a bit hard to try to figure out what to focus my attention in studying. I would also say time-wise I feel that he puts way too many questions for his 50-minute midterms which is why he always has to add more time for us (and he acts as a ticking time bomb by constantly telling us the time we have left but refusing to just put an actual clock on the screen). I think that he also likes to give students test anxiety by writing on the board mid-test for whatever he is trying to teach right after our midterm that like half the class isn't really listening anymore for... But overall, I really enjoyed his class content and also his office hours were always super informative, whether it be just asking him advice for doing research, asking him questions about extra information from the textbook, or asking him to reexplain concepts. I liked him as a professor but was definitely not a fan of his tests.

Overall, the class was difficult, but very interesting and informative. Although tests were challenging, the questions presented opportunities to think conceptually or outside the box. The grading is somewhat curved, but around 40-50% of students get an A, so if that's your goal, just aim for that rank in the class. Professor Ong is an amazing lecturer who presented the material in an engaging and clear manner. Prior to this class, I found physics annoying and difficult, but after this class, I found physics intriguing, and I found myself wanting to learn more outside of class. Lastly, Professor Ong did numerous demos, which effectively demonstrated concepts rather than just lecturing.

Uses past exam questions so check test bank. Has a weird grading rubric for exams. I did the worst in this class of the three honor physics classes

He's the goat ONG

Out of all of the 1H series, this class was by far the "easiest", but that does not mean that the class itself is not difficult. The material is rather more straight forward to learn compared to the material of 1BH and the problems are not as difficult as 1AH. You start off the class reviewing some Waves and E&M and then go into optics and sound, with the more conceptually difficult portion being that of diffraction. You then cover some fourier analysis and special relativity. Overall, Professor Ong is a really approachable guy that has really engaging lectures and often brings demos every lecture. If you want to take a class that is a bit more challenging and covers topics that you probably aren't going to see in regular 1C, take this class.
