Wow, this is a really hard class. I know it says that any physics background is not required, but the class is structured to go more in depth on topics you should already be familiar with. That being said, if you excelled in AP Physics in high school, I'm pretty sure you will be fine. Beware though, the class is filled with physics majors who already know everything the Professor is teaching, so the pressure to excel is very high.

That being said, her grading scale is very, VERY lenient though. I scored super below the mean of every midterm and did OK on the final and still finished with a B. I guess it is a fair trade for the competitive atmosphere of the class (which is not the Professor's fault, it's just that the students who take this class are those type of people). I STRONGLY suggest to find someone in the class to help you with the material if you struggle with physics. I assure you there's always that one Physics major who has nothing to do except talk about the subject they love most and fluff up their ego a bit. Use that to your advantage.

If you're not a physics major and don't have something to prove, you do not need to take this class. Introductory honors classes are already hard, and taking one not related to your major is even harder. This will whip you up into a pseudo physics student in the harshest and fastest way possible. I will say, taking this has made my 1B class so much easier. Good luck!

This is a hard class. That being said, the professor grades generously, rounding the average grade to a 90% at the end of the quarter. Plus, the professor is super kind and helpful; she was constantly looking for student feedback on how homework problems and midterms were so she could improve them in the future. She will sometimes skip steps during lectures which can be very confusing, but all you have to do is raise your hand and ask a question and she'll clarify things. For the class I took, the grade breakdown went: homework problems (10%), two midterms (each 25%), and the final (40%).
You're given on average 6 problems per week for homework, and you're expected to work on each one for about an hour. The textbook and solution guide are offered online, and the TA and professor almost expected you to use the solution manual for hints/solve problems, given that you're still doing the work yourself.
Each midterm had three problems broken down into multiple parts, and you're given an hour to complete the test (so on average 20 minutes per problem). You're also allowed 1 sheet of printer-sized paper where you can write anything on the front and back. For every test she gave, she always put on a problem from the notes and/or homework, so make sure to copy those down. The main challenge of the midterms is the limited time—the problems themselves aren't that bad (they're much easier than homework problems) but being able to know how to solve them quickly and to not panic can be difficult. My advice is to not only do additional problems from the book for practice, but to redo problems you've already done in class/homework to the point where it becomes second nature. Also, oftentimes, about half of the points for problems are related just to setting up the problem, so if you have a question which requires a lot of work (I'm thinking particularly of collision problems), I recommend writing down the constraint equations and then moving on.
The final is twice the length of the midterm (6 problems) but with 3x the time. We could have two sheets of paper to use during the exam. Because I had extra space from my midterm cheat sheets, I just used those and added notes from the new topics covered in class. The only reason I got an A in this class was because half of the exam I could copy down from my cheat sheets, allowing me to score way above the average (for the midterms I was exactly average). The professor made oscillations the biggest theme (three of the problems were related to oscillations, with two of them being derivations).
This was by far my most difficult class my first quarter, despite receiving a 5 on the AP Physics C Mech exam and thinking I had a fair grasp on the subject. Unless you're a genius, expect to put in a lot of time and effort into this class. While it was a struggle, the class did give me a deeper understanding of physics and taught me learning strategies that I will take with me into the rest of college.

Phenomenal class -- the professor did a great job of covering all material, expanding on concepts, and making sure your time spent in class felt valued. However, as a first quarter freshman I was not ready for how intensely I would have to study in this class to succeed, especially because it assumes you have taken AP Physics C and some parts of multivariable calculus before this class. If you put in the work though, you will realize how much this class improves your thinking and problem solving skills. The tests are tough, like 60% averages, but are curved so that the median is ~90% which is very generous.

Easy class. Would take again.

Physics 1AH is the hardest class I've ever taken, and I actually cried in class once because I was so lost. That being said, office hours is very helpful and Bozovic is very nice with re-explaining concepts. Grades are scaled very nicely. The homework is impossibly difficult compared to what she asks on midterms and finals, which are much more similar to in-class examples/easier homework problems she gives the solutions to. An A or A+ is definitely achievable if you put a LOT of time into the class, especially since many midterm/finals problems are explained in class. Overall, I'd recommend taking this class if you have a decent physics background and/or enjoy it. Otherwise, it is definitely a challenge.

Since this is an honors physics class it is understandable that the class would be difficult. The Professor gives very engaging lectures and I feel that she taught pretty well. She also is very approachable, setting office hours outside of class and even giving breaks in the lecture.
Your grade is comprised of the Problem Sets (6 of them for this quarter), 2 midterms, and the final. I am not a great test taker myself so the exams were pretty difficult. Your final grade is scaled with respect to the median score of the class.
If you want to challenge yourself and get a lot out of a physics class, by all means take this class. While it is difficult, it is also pretty rewarding.

First midterm extremly easy, second midterm a bit hard. FINAL IS ABSOLUTELY DISASTER! However, the professor gives excellent lectures prepares you well with further physics courses.

This was by far the worst class I have taken at UCLA. If you have not taken a physics class with calculus and don't have working knowledge of the math from every lower division math class taught at UCLA you are going to have a very hard time in this class. Professor Bozovic taught this class assuming that everyone had seen all of the material before and her job was just to do very hard example problems and proofs. I understand that this is an honors class, but that doesn't mean it shouldn't teach the material that is covered in the non-honors version of the class and test reasonable questions about it. I'm not saying that there shouldn't be hard problems, I'm simply saying that there should also be problems that allow you to demonstrate your understanding of the essential subjects being taught as well as more difficult problems to challenge you. There is no listed physics knowledge requirement for this class, but it is taught assuming that everyone already knows the material that the class should teach which is absolutely not how any class should be taught. The professor seemed to think that because some smartasses in the class already knew all the material as well as all lower division math material through 33B that everyone in the class knew it while this was certainly not the case. There was a differential equation problem on the first midterm and several double and triple integral problems on the final which is NOT material covered in any pre or co-requisite for this class. Additionally the TA I had for this class, Nick something, was not helpful and very cocky even though a huge majority of the time when you would ask him a specific question he wouldn't really have an answer or he would have to look up the answer in the solution manual. He would show up to section with like 3 problems prepared that he would do and then act like anyone who asked a question about those problems was an idiot while he wasn't even able to do a problem from the book that he hadn't specifically prepared for when you asked him about it in office hours. A total waste of a quarter that made me hate physics and switch my major. If you take this class and enjoy it then it was a waste of your own time too because you clearly already knew all of the material before taking it.

Professor Bozovic is a very good Professor. Highly recommended.
The lecture is clear and understandable. It might be a little fast, but it is Honor class so it's ok. It includes a lot of derivation of the formulas which I think is neccessary. She has light accent but it doesn't matter. She might make some mistakes on lecture but she will fix that at the beginning of the next one.
Homeworks are not hard, and it's not hard for you to find a solution online. There are 6-8 problems per week with medium difficulty due every Friday. No homework during the Thanksgiving break and that's awesome.
She has 1 hour for OH every week since 1AH is not a large class. I've been there 3-4 times and learned a lot. There aren't many people so just go to OH, don't asker by email. You could ask whatever you want to know, and I think I learned a lot.
The first midterm was extremely easy and I think most of us got above 90 out of 100. The second midterm is ok and the median is around 60. Final was a disaster. Grades were curved so I don't know exactly, but everyone looks like "what the fuck is that" after the Final.
Generally speaking, I highly recommend her as your first Physics Prof in UCLA if you are physics or Engineering students (otherwise it might be hard).
