Dr. Scerri is clearly a very knowledgeable in the field of chemistry. That being said, he often times explains concepts as if we already have a strong understanding of this material, making it very difficult at times to follow along. The grading structure consisted of 50% of our grade being 4 quizzes which we had 3 attempts on, 20% our midterm, and 30% our final. The quizzes were fair, however, the midterm and final were both very difficult and rushed. He simply did not give us enough time resulting in poor results on the tests. Though the practice exams were similar to the questions he gave us on the test, they often had wrong answers on the key he provided, leading us wrong for what the correct work and answer should be for the actual exam.

Furthermore in light of COVID-19, he was not accommodating. Not only did he give unfair exams, but he also curved the class down significantly at the end of the quarter. He did not send out any reasoning for this curve nor did he offer the final numbers for the class. Instead, we received our final grades with no explanation which is both disheartening and frustrating. As a whole, the class was one frustrating experience after another and was not a pleasant experience.

Before taking this class, I was warned by many people that I should NOT take this class. After taking the class, I would give about the same advice to my peers. The professor does not use actual slides, but rather PDF documents with often unorganized information. When asked questions in class, he often took a long time to answer the questions, and sometimes just avoided the question entirely. It was clear many times that he did not really review his lecture slides before class. It seemed to me that he didn't really care for his student's wellbeing, as evidenced by the fact that he told students to never use his personal email and to only post things on the discussion forum (which he also rarely checked/answered). The exams were not too bad, especially given that they were open note, but I relied heavily on AP Chem knowledge to pass the class. If you can take the class with a different professor, please try to do so. If you cannot, make sure you attend TA sections (because the TAs are sometimes or usually better at explaining the information than Scerri) even though they are not mandatory, do a lot of practice problems, and watch a lot of Youtube videos on concepts you don't understand.

I would like to think that Dr. Scerri has turned a new leaf. His exams used to be upwards of six questions with multiple parts, complicated equations, unclear directions, and every other atrocity you could think of. In light of his bad reviews, this quarter he opted to make the exams more organized, succinct, and tolerable.

Our midterm was rather pleasant, actually. Our tests were curved up and I was one of a few students who got 100% (sorry but I hope that gives context as to who's talking here).
The midterm was based on practice exam questions we had gotten during discussion sections, and his previous exams were a great litmus test for what types of questions we would expect.

The final exam, however, was an entirely different story. Because of the TA strike, our exam with multiple-choice on a Scantron. The multiple-choice questions were adulterated from the same online source and Prof Scerri lacked the common sense to supply us with the necessary information to approach these online questions. Because of this fault, 5 of 45 questions on our final exam are being omitted, with a 6th question having answer options from an entirely different question (formatting issue?). Compounding this, students with the CAE were told that they were five questions to omit and not approach, but students in traditional lecture halls are only told about four. For this reason, we are currently running the risk that students with accommodations will have an artificially lower score because they were told to leave another question blank.

Take this as a testament to his communication style: he sucks at it.

As other reviews have indicated, his lecture slides are incredibly unorganized and his style of walking us through lecture slides during class with occasional elaboration does little to aid our comprehension.

While I might not be as direct as the other reviews to "Avoid Scerri at all costs," I would advise that you might want to avoid him if unorganized slides, a lack of communication skills, a snobby personality, and a stark tendency to say "obviously" when trying to explain challenging concepts are a deal breaker to you.

Thank you for listening to my TedTalk.

I actually really loved this class. From the students I talked with that were also in the class, this seems to be one of the most polarizing classes I've been in. You either love it or you hate it. But that makes sense, since general chemistry is often a weeder-type class for many pre-med students.
I will say this though: it's possible for anyone, even if you're not "good" at chemistry, to get a good grade in Eric Scerri's Chem 14A and have an appreciation for the material.
40% of your final grade in this class is the final exam, and 30% is the midterm. Dr. Scerri will give you several old exams to study and STUDY THESE!! Even MORE importantly, go to the test bank and search for as many old exams as you can find. Split it up between you and your friends to get literally as many exams as possible. These past exams are very useful because Dr. Scerri has been known to copy and paste pretty much all of his exam questions to his current exams, or he may change a single word or number. Understand how to do problems on as many practice exams as you can find and you'll be golden. I got a 98% on the midterm and a 97% on the final through this method, because as I reviewed more and more practice exams, the problems that I had with the material eventually disappeared. I can guarantee you that people who don't do well in this class don't do this.
20% of your grade is online quizzes, which aren't too difficult, and 10% is homework, which can be quite tedious but is overall manageable. Scerri is very funny at times, but can also be quite dull at other times. However, I would say he's in the better half of professors I've had at UCLA. Don't even bother wasting money on the textbook.
Lastly, going to discussion definitely didn't hurt me either. Some of the more complicated concepts such as molecular orbital theory and hybridization were ironed out for me through my TA's teaching.
Overall, this class is manageable, and the resources for you to do well are definitely there.

Oh where to start with Professor Scerri. As you can probably tell by the other reviews, Dr. Scerri is not a very good lecturer. His slides are extremely confusing and he often gets confused trying to explain them to us. More often than not, a TA or student has to correct him because he gets confused. Apart from the bad lectures, the tests are not only very difficult but are also a huge time crunch. The practice exams he gives out are so much easier and shorter than the actual tests (they also have incorrect answers on them). The midterm he gave us was 7 free response questions with like 4 or 5 parts each in 2.5 hours. I barely had time to finish despite going fast; I did not have time to check my answers, but Scerri obviously did not take any criticism the class had for him because he did the same thing for the final. He said he would try to make it better by adding multiple choice questions, but those MC questions each had 5 to 7 parts as well. So he ended up giving us 6 free response with parts a,b,c,d,e along with 12 extra questions for multiple choice. He said this was to deter cheating to make sure we couldn't consult anyone else in the class, but many people along with me could barely even finish on time.

In addition, he doesn't seem to actually have much regard for his students, unless you're one of his favorites. One time in lecture, someone asked why he used a certain amount of sig figs when dealing with pH which was a valid question because it was confusing and he answered with "have you been coming to lecture?". This was a completely inappropriate response. I had come to every lecture and he had barely gone over that concept and I found his entire demeanor to be very condescending and smug. On multiple occasions you can literally see him rolling his eyes at some questions also.

Personally, I did not enjoy 14B with Scerri, but it is possible to get a good grade if you commit yourself. Honestly, the best way to study for his tests are to do the exams he gives out as practice (and ignore the incorrect answers he gives), and watch a lot of the Organic Chemistry Tutor on YouTube. If you have to take 14B with Scerri, I wish you the best.

Scerri is one of the worst professors I have taken at UCLA. His teaching online was not the best because the class requires a lot of math problems so he would mainly say how to solve them instead of actually be able to write out the steps, this of course was simply due to the online format. I think he is okay to take in person, where you can form study groups and ask questions. But he was very unaccommodating to the current situation and expects everyone to come in with solid knowledge of chemistry. His sarcasm during office hours and lectures made my blood boil. If you have the chance, take any other Professor.

He's a great lecturer. BUT he can be very rude and arrogant. I went to his office hours and he was NOT helpful. He was very cold and unwelcoming and repeatedly said "We went over that in lecture". If I had understood it well enough in lecture, I wouldn't have gone to his office hours in the first place! He answered my questions so quickly that he was basically brushing them off. I could tell that he wasn't really interested in repeating himself or trying to explain things clearer in any case.

So basically, a talented man and an organized lecturer, but an arrogant one who doesn't really make teaching his priority.

Believe ALL the reviews posted for Scerri, no matter the course, and I know there is a lot. If you are thinking about taking chem 14A, DON'T TAKE IT WITH SCERRI. His class is a mess, disorganized, and not fun at all. During class time (took this class online because of COVID), he just reads off his lecture slides word for word. Often focuses on the history of chemistry instead of actually solving problems. When he does show us problems, he doesn't physically go through the problems with you and because this is an introductory course, it's kind of important that he does. For midterm and final "reviews" he just combines all his slides from past weeks into one big slide and spends the class time reading them word for word, just faster. You're better off not attending lecture, just discussion. (He interrupted multiple lectures by asking why no one had their cameras on instead of focusing on teaching. When we gave reasons (internet connectivity, more cameras on = lagging issues, distractions, etc) he basically dismissed them and said they were stupid and untrue.) Discussions aren't mandatory but they're IMPORTANT if you don't want to listen to Professor Scerri. In discussions, TAs help with actually solving problems and what they mean in the context of the class. I had Spencer as my TA and he was a GREAT help. Besides 1 midterm during week 5 and the final, there are 9 Sapling quizzes you have to do. He doesn't offer any schedule to do the quizzes, just one big deadline at the beginning of week 10 so you have to create your own or you can choose to save them until the end of the quarter (I don't recommend this though). This class is heavily curved but you'll survive if you learn to work well with your peers and ask for help. Join a PLF session and talk with your peers on help with sapling quizzes. Class only consists of 3 grades: Sapling, Midterm, and Final. Our midterm was very easy with almost all questions copied word for word from another exam in previous years but for the final, it was devastating so don't think that you can float on by in this class.

tldr: This class is messy from start to finish. Don't go to lecture; go to discussions. Try to get Spencer as your TA. Sapling is required and try to finish one quiz a week to be on track. Midterm is easy but final was excruciatingly hard. Class is curved. Get help from PLF sessions. Grade consists of: sapling, midterm, and final. If you're in this class, you can text ********** for pdfs of past midterms and finals with answers (as well as blank ones so you can practice with).

Professor Scerri is horrible. I agree with the people below that like his course reader because you do not have to buy a textbook, but he is a mess. His lectures are all over the place. His office hours are useless. And his finals are ridiculous. Science majors, there is no way to avoid him...sadly! But if a new teacher comes along...take them no matter what!

dude this class was bad... scerri is incomprehensible and terrifying. the course is reasonably difficult (what you'd expect for a chemistry class) but scerri is a terrible teacher and is entirely unclear about what he wants you to know.
the homework is fine- its a bunch of modules due at the end of the quarter. totally manageable but not really helpful for exams.
the ta's are helpful for the most part. sometimes they seemed to be just as lost about how scerri approaches certain topics, and will just teach you a different way. theyre as helpful as they can be with what theyre given, and i definitely suggest going to discussion. attendance isnt taken for discussion or lecture so you can pick which TA you like.
ive heard that other sections of 20a have much better professors. do everything you can to avoid scerri. his slideshows make absolutely no sense and wont walk you through the kinds of problems youll see on the exams. he's going to be incredibly vague about what will be on the exams and what info he will give you on the formula sheet. he doesnt really stop for questions and will make you feel stupid if he doesnt like your question. he's really terrible at gauging how his students are feeling or how much we're learning. the first lecture about quantum mechanics will be comically difficult and scerri will simply push through.

shits tough. cant wait to take a chemistry class with a decent professor.
