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.

This guy wasn't that good for me. He's whatever.

Scerri is a good lecturer and professor. In class, he often goes through the material at a rapid pace so it's hard to learn in class unless the concept is really easy. He doesn't have his lectures recorded which makes you show up to class. Despite general confusion in lecture, this is where discussions bridge the gap between what was taught in class and what you retained. The class was easy if you were able to cover the material after lecture and understand what was going on. You will need to study for the tests, if you don't, expect to fail.

Lectures: Attend every lecture because if you don't you will have to learn the concepts on your own from the slides and it will be much harder. Scerri is able to explain the concepts well and, lacking this, will make it much harder to learn.

Discussion: It really doesn't matter which discussion you go to. If your TA sucks, go to the other TA's. The more TA's you go to, the more practice you will have before the midterm/final. Each TA will give you a deeper understanding of the concepts and from a different perspective. I went to every TA discussion in the week and found that even if I already understood what was going on, it was beneficial.

Office Hours: I never went, but I've heard they're helpful.

Tests:
The tests are relatively difficult and you should prepare by using the test bank, reading the book, and doing the owl questions(BEFORE the test). From what I've gathered, he likes to ask at least one extra challenging question on the test. The tests aren't impossible but if you've never encountered the question before it's going to be difficult to figure out the correct answer. The formula sheet he gives doesn't cover all the questions as some you have to memorize to get correct (derivations or recall). The content comes from what he's discussed in lecture so really no surprise there, you just have to understand what was going on. There was only one midterm this quarter and I think the average was a B/B-. Studying for 2 days straight going over the released midterms and memorizing them until the early hours of the morning paid off and that was enough to succeed on the test.

For the Final: Thoroughly go over as many finals as you can get your hands on. Most of the questions are small revisions if not the exact same question from other finals. If you know how to run through a question, you will be able to do so on the final. I noticed he liked to repeat rather challenging questions that students often got a 0 or partial on. Study those challenging ones so you will be able to answer them if they appear.

Grading: He grades the class on a curve. You can't do average and expect to get an A. You have to work harder than 90% of the class if you want to score as such. You won't find out how well you did on the final until the next quarter. The grade you see is the curved grade, not the grade on your final.

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.

This was my first ever chemistry class and I have left this class absolutely hating chemistry. I read all the reviews beforehand and thought to myself that this class can't be that bad and is probably manageable but I could not be more wrong. Scerri has ZERO organization on his CCLE site and his lectures make absolutely no sense and consist of him jumping from one topic to another back and forth. I did not even know what the topics were so I can study on my own since there is no OUTLINE. The exams were extremely long for the duration and I have not learned one topic in this entire class which will harm me going forward in the course as he is the only professor teaching 14B next quarter too. This class was so bad that I almost dropped and changed to a non-stem major every week. DO NOT EXPECT TO LEARN ANYTHING.

I agree with what people said below. Just make sure to include EVERY detail on the test. That makes all the difference. You may know the problem like the back of your hand, but if you leave out some minor detail, they leave out some major points. Oh, and make sure you have a good TA.

*Grading/Curve*
Dr. Scerri is probably one of the most polarizing professors I have heard about. I think a lot of people dislike his classes because he is not very clear about the "curve." He stated on the first day/his syllabus states something about not wanting too many people to get A's so some people do get curved down. This did happen to some of my friends unfortunately who had about an A and were given an A-. He is not transparent at all about how much he is curving people down or what the class average is etc. Additionally, your final grade may not accurately reflect how you performed on the assignments since Dr. Scerri does make mistakes when inputting final grades. This happened to me and my friends, but I emailed him and went through some back and forth, but he eventually changed my grade. Your grade is 30% midterm, 30% Achieve (homework), and 40% final. No extra credit, syllabus quiz, discussion, participation, etc. -- just those three assignments.

*Homework*
Achieve is a pain since it is graded on accuracy and some of the problems require sm time and are too extensive for what we are tested on. DO NOT LEAVE THIS TO THE LAST DAY. I think it is manageable to do in the last week, but this can be VERY stressful when studying for other finals, so I highly do not recommend doing the whole thing the last week either. The numbers will also vary from student to student so you cannot "divide and conquer."

*Exams*
Personally, I am very bad at chemistry and only took one regular chem class early in high school so everything I learned in 14A and 14B was new. However, I did some of the old midterms and finals Scerri posted and they were highly similar to the actual exams since he reuses his exams. I definitely recommend doing the old exams before studying your notes because it will help you narrow down what you need to study. The answer key for these exams are usually wrong though so you have to check with a TA for the right answers. He does not use the textbook at all and all the concepts/problem types can be found on his lecture slides. Study his slides if you have time!!

*Lecture/Content*
Lecture attendance was optional since they were recorded, but I actually really loved attending lecture. Dr. Scerri is a very amusing lecturer and I found the content very interesting. His slideshows are unorganized since everything is in different colors and fonts for no reason, but his slides have a lot of useful information and diagrams (some of which you will have to draw on exams!!) Honestly, if you put in a decent amount of effort, the slides aren't as hard to understand as other reviews state. People say that Dr. Scerri is a confusing professor, but I think that's just the content in general. He really does try to thoroughly explain the material and pauses to ask if we have questions. He even makes jokes and takes a break every now and then.

*Professor/TAs*
I had Dr. Scerri for both 14A and 14B and I had very low expectations because of the previous reviews, but after finishing both classes with him, I actually really liked him and his classes! I wouldn't say he's the nicest professor, but in both quarters, I have never heard him be rude to a student. He is very open to answering questions and usually is responsive to emails. He definitely gets a bit confused from time to time during lecture, but he will correct himself after a couple of minutes. Your understanding of the content is definitely reinforced/enhanced by the TA. I had Hootan, who I 1000000% recommend, but I've heard Spencer and Kodi are also amazing.

You can't be a bad professor and be rude. Seriously the worst professor at UCLA. Whatever you do try to take this class with Lavelle! Received an A+ in his class due to the enormous amount of support material he gives his students. Scerri on the other hand, reads off of his bullet points and insults his students when asking a question.

I don't recommend this class to anyone who wants to maintain an interest in chemistry. If you have to take this class with him here is the rundown:
HOMEWORK: As of Winter 2020 he uses OWL for homework. It 's like 10 online "quizzes". All the homework is due at the end of the quarter and it's free points basically because they give you 10 tries on the same with different numbers/elements and tell you how to get the answer if you get it wrong. Unlimited time on every "quiz".
TEXTBOOK: There is a textbook that comes with OWL. I never used it.
LECTURES: Possibly the worst part of the class. Not bruincasted, and he posts the Powerpoints but they make no sense. Like actually ZERO sense. Worst formatting on earth, barely any insightful content. When he goes through them in class, there is slightly more clarity. Slightly. He is not a great explainer for complex topics, moves rather fast for no reason, and does not answer questions well. After the first midterm (Week 3), I stopped taking notes and attended intermittently.
TESTS: These are his only saving grace LMAO. Purely based on previous tests. Your TAs should give you a packet of his previous exams. LITERALLY just do these and memorize them and tests are a breeze. Only caveat is most of them do not have the answers so check with someone or ask your TAs if you want.
TAs: I believe this is where you'll get the most actual learning. My TA was not that great, so I attended other TA sections. They can be pretty helpful and are usually better teachers than Scerri himself. If you don't life your TA, DEFINITELY try the others. Attendance didn't really matter at all.

TLDR; don't take this class. if you have to just make sure you go to TA sections and do the past exams.

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.
