    At first it started off rough but eventually he got his stuff together and ended up being a great professor

    class was organized with the lectures but there was a lot of material that the proff expected students to know beforehand.

    He was a bit unorganized at the start, but got much better at teaching. Make sure you review the slides he posts and (maybe) take some notes.

    Grade: A

    In the first few weeks the lectures were pretty disorganized and we were expected to know a lot of the information beforehand, but it got a lot better towards the end of the quarter.

    This class is essentially a repeat of AP chemistry, but even if you didn't take it, I think Toumari's exams are fairly basic enough that you will be able to succeed by paying even just a little bit of attention. The homework is a good representation of how the tests will look, so as long as you do the Achieve assignments, you should be good to go.

    It was like AP Chem if you took that in high school but easier. Toumari was just very particular with small insignificant details just to make students lose points.

    It was honestly kind of hard taking this class with Toumari because he wasn't the best at lecturing, and I had the TA strike going on at this time. His lecture slides were quite vague, and his explanations to the topics or practice problems were alright. The TA's were more helpful at explaining the topics, and were better at leading the practice problems. The quizzes Toumari gave were quite difficult because they were timed for only 10 minutes... and they involved long problems that would usually take up to 5 minutes to complete. Overall, his class was quite stressful because of the way he structured things, and because of the TA strike. I think if you had a background in AP chem, then you should be okay taking it with Toumari. But if not, then I recommend reaching out to your TA as much as possible and reading the textbook.

    Toumari was an okay lecturer. I think I did well in the class just because I had a background in AP Chem in high school. I have a friend who took 14A with only regular high school chemistry who dropped premed because of it, so I think this class is definitely much harder if you aren't mentally prepared for how challenging it is, especially if it is one of the first classes you take at UCLA. I did really poorly on the first midterm because it's a tough first class, but I managed to pull it up to an A. I think that there is plenty of room for correction later on in the class, but definitely focus on completing practice problems and understanding the concepts and you should be fine.

    Worst professor ive ever had. Class average for the midterm was rly bas (i think about 70%) and he said he didnt know what a curve was. he was inconsistent with responding to emails and his lectures made no sense most of the time. the only way to learn anything was by doing practice problems.
