Professor Randa Reslan is the best choice for taking 14A with. Her lecture was thrice a week MWF, but attendance isn't mandatory and I'd honestly recommend just rewatching the lectures back at 2x speed. We had "weekly" problem sets on Achieve that kept getting extended that were anywhere from 8-20+ problems that were based on the textbook and lectures. The grading scheme is as follows.
10% Homework
5% discussion section worksheets (you just show up for attendance)
35% midterm exam
50% final exam
There was a bonus LA survey that added 0.5% to your final grade. For the exams, I would recommend going back through the problem sets and making sure that you understand each problem and how to get the correct solution. She records decently long review sessions (two 2 hour review sessions for the midterm and four 2 hour review sessions for the final) and also uploads practice exams that are similar to the actual tests. She is a very accommodating and nice professor (during the midterm, because of the unrest going on on campus, she decided to curve the midterm). Reslan added 6 bonus points on the final (126/120). She truly cares about her students and is an amazing professor, and I would never have taken 14A with anyone else.

Professor Reslan is an awesome professor who truly cares about her students. The review sessions she hosted were very helpful. Tough material but Professor Reslan's teaching makes it bearable and easily understandable.Cannot recommend this class enough!

When I took 14A with Reslan, it was her first time teaching at ucla. So of course, she's not gonna be perfect, and at times she was a bit disorganized and made few errors since it was her first time teaching the quarter system. Many students would hate on her and wouldn't appreciate what she did for the class which pissed me off. However, from her growth and quality as a professor, I would say she is an amazing professor and the majority of the students with a brain would agree. If she is teaching this class again, take it with her! After the first few weeks, she assimilated into the class, became way more organized, and more helpful in our learning. The exams were so fair and similar to the practice in the class. She provides so many practice problems and wanted us to get an A. She tried her best to simplify complex topics and would try to answer as many questions as possible. She was also extremely nice and accommodating (even though she had to deal with some annoying ungrateful students so I felt bad for her throughout the quarter). She might have changed her class structure from when I took it, but overall, she is goated, so take the class with her!

I loved this class. I am not a chemistry person in the slightest and have always detested it in the past, and by no means did she dumb the class down, but she made it very approachable and frequently said she wanted everyone to succeed. She is a good, clear lecturer, and provides very good practice exams. She provides outlines for her lectures printed to write on, and would provide a filled version later so you could make sure you had the math worked out right. The content on the exams was never a surprise and never a trick, and matched the difficulty of the practice problems very well. The exams are forgiving in that there were sometimes two long questions worth the same amount where you needed only to choose whichever one you preferred to answer. The final was all multiple choice so did not have that, but it did have extra credit questions to pad the grade. I don't think I've ever learned more from a chemistry course, nor have I ever taken one so low stress.

I am not a fan of chemistry, but if you have to take 14A, I recommend professor Reslan. She was slightly disorganized at the beginning of the quarter, but everything was running smoothly by the end. She is very caring, will always admit to and remedy her mistakes, and often sides with students' wishes. I struggled initially, but she took time to hold helpful office hours, which I highly recommended attending. She also curved the final grades, which I believe helped many people.

Definitely love Reslan, she taught chem in a way that made it pretty easy to understand, and this is coming from someone who definitely dreaded starting this series. The way I approached the class was to do the textbook readings, which was overly difficult to understand, and then attend her lectures where she taught them in a more understandable way that helped solidify it and make it seem easier. She was very accommodating for the students and ended up giving so many extensions for the homework (in my opinion they were even unnecessary tbh). She curves the exams depending on the class average, so they ended up curving the midterm but not the final. My only issue with her is that she is pretty slow; we ended cutting out 2 topics we were supposed to cover, and the second half of the class definitely felt faster than the first half. Otherwise, she is definitely a great professor to take chem with.
Grading breakdown:
10% homework (8 Achieve practice sets, the first half were like 15-20 questions each, the second half were like 5-10 questions each; you have unlimited attempts to get each problem right)
5% discussion (just based on attendance)
35% midterm
50% final

This class is relatively easy. Weekly homework with 10 questions each and mandatory discussion attendance. But other than that, it's pretty free. The midterm and final were easier than the homeworks. Reslan is kind of boring in my opinion, so I just read the lecture notes and never showed up to lecture.

reslan is a little bit everywhere when she teaches, but i loved the fact she had physical packets of her lecture slides so you can follow along and I found it super helpful since it was on paper. the midterm wasn’t terrible but the final was pure multiple choice and practically a bunch of conceptual questions and it hurt me because i practiced on the questions we go over in homework and discussion and it didn’t appear anywhere. also the final was mc because of the strikes. MY BIGGEST COMPLAINT IS THAT THYE SAID THEY WOULD CURVE THE FINAL DUE TO THE STRIKES AND PROTESTS NO MATTER WHAT THE AVERAGE AND THEN THEY DECIDED TO NOT CURVE IT BECAUSE THE AVERAGE WAS AROUND 80%. they basically ignored piazza questions regarding this and then “curved” it by adding a point. overall, they were probably the most accommodating regarding the protests that happened but it just got really jumbled and difficult towards the end.

Randa is a really nice professor and I could tell that she wanted us to succeed. I did super well on our midterm, but fumbled the final (which was my fault). She truly gave us all of the info and made our exams super reasonable based on what she taught us. I’d say she’s a pretty good lecturer too. Def try to take 14A with her if you can.

Dr. Reslan is amazing, take her if you can! Chem has always been one of my better subjects, so I can't speak too much to the difficulty of the class, although I will say that the majority of it is just knowing when to use which equation (and you're provided an extensive equation sheet on exams). As far as lectures go, I will concede that Dr. Reslan isn't the best at explaining and spends most of the time doing derivations that we don't need to know, but she does want everyone to succeed and is more than happy to go over concepts multiple times if people are confused. She is also extremely accomodating. In a quarter with weeks of online class, cancelled discussions due to the TA strike, and a general sense of unease due to campus conflicts, she was the ONLY stem teacher I had that made any effort to help. She changed our final to multiple choice, lowered its weight, and gave us three free questions. She even switched the weighting of the midterm and final if it helped your grade. She held multiple review sessions in which she went over problems similar to exam questions. She also seems to be taking feedback seriously (since she removed derivations from exams). The TAs were also amazing, and I was able to master the majority of the material just from attending discussion and doing the worksheet. Homework is on OWL and has 10 attempts per problem, so you're basically gauranteed full points. OWL was an amazing resource to study for the tests since the test questions were very similar to the homework problems, and the website had a practice option that made studying super conveneint. All in all, the class might seem scary since exams are worth so much, but the exams are reasonable and and A is definitely achievable if you put in the effort.
