    CHEM 14B with Lavelle followed the same format as CHEM 14A with Lavelle. Lavelle is a great prof if you've had some exposure to AP Chemistry.

    Lectures were presented clearly and there is a lot of information/resources provided incase you don’t understand. I recommend using homework and textbook practice problems in order to prepare. The content seems intimidating but enough practice will help you understand and prepare you for exams. I recommend going to office hours for any questions.

    Distribution: Chemistry Community: 50 points Weekly Homework: 50 points Midterm 1: 80 points Midterm 2: 80 points Final Exam: 140 points Dr. Lavelle is a great professor, who has clear and engaging lectures. The workload is extremely manageable with the required homework not being long, and Chemistry Community simply being an online forum where students can ask and answer questions (you're required to post/answer 5 times a week, 50 by the end of the quarter). The required homework problems have unlimited attempts. There's also recommended textbook problems, which I definitely recommend doing, as a couple of the problems are on the exams. Chemistry Community is also a very helpful resource, and Dr. Lavelle and other students are very active on it. UA sessions are also an excellent resource for extra practice and to ask questions, with sessions being available daily. The lectures are also recorded and uploaded in a timely manner. The exams themselves were all online and were pretty straightforward (mix of conceptual and calculation questions with 4 pt and 8 pt questions, 8 pt questions having partial credit). One of the questions is always given beforehand in order for you to test the lockdown browser. There were 15 questions (1 hour) on both midterms, and 25 (1 hour 45 min) questions given on the final, which was ample time to complete the exams. My exam scores were 68/80, 80/80, and 140/140. The way I reviewed for exams was to review lecture notes and recommended textbook problems.

    Practice problems are your best friend!! Make sure you can do the textbook questions, and you will be fine for this class

    Much harder class than 14a. Lavelle still a good lecturer, but taught us derivations that weren't very helpful. All resources provided were very useful but amount of time available to use them all effectively was the linchpin. Barely scraped by and got an A. Tests multiple choice but still very hard and no margin for error.

    While lavelle preaches using the textbook, understanding the concepts conceptually is far more important and adheres more closely with the mc format of the exams.

    Class fairly difficult for someone who didn't take AP chemistry. Lot of time spent reading the textbook, as the lectures didn't really serve much utility in terms of learning, and are rather better off used as supplement to the reading. Sometimes lectures can be spent going over how equations are derived, rather than how to use them, and it will depend on you how useful you see it.

    the lectures were clear and easy to understand but a lot of the content on the tests were not covered in practice problems or lecture making it difficult to know how to prepare for exams.

    The lectures were super confusing, and the exams were all multiple-choice and very difficult, meaning there was no partial credit. Although he was a very nice guy, he was not great at teaching the material.

    It was honestly super easy. I never went to class and never even met Lavelle and I got 100 on both midterms and the final. I just did the homework and the study guides the night before each exam. Everything is given to you to succeed.
