Winter 2020 - Professor Courey was, without doubt, the best professor I have had during my time here at UCLA. He is very passionate about teaching, and it shows when he lectures. He posts the PowerPoints for lectures ahead of time, and there is a quiz that corresponds with almost each PowerPoint. You have unlimited attempts on these quizzes, and to encourage you from guessing your way through these quizzes, he awards you a point of extra credit for each quiz that you get a 9/10 or higher on in under 2 attempts. His first midterm was pretty hard, and time was extremely limited. However, he realized this, and allowed us to gain back some of the points we missed. Also, he made the second midterm significantly easier, and I think it was because of the feedback he received on the first midterm. The final was not super easy, but he was very understanding of the circumstances, considering it was during the whole coronavirus frenzy. He made it optional, but if you were to take it, you had ample time to do it. In addition, he allowed us to collaborate on it, and gave us the opportunity to earn 10 points extra credit on it. We had weekly homework due, but these were graded on effort, and we would go over some of the problems with an LA in our discussion, which clarified the concepts well. Overall, Professor Courey is a gem, and I would definitely take a class with him if I could!

Winter 2020 - Same format as his Chem 14A class. Due to COVID-19 however our final was changed to an online Multiple Choice quiz, which for sure was WAY easier than any 3-hour exam he could have made in person so my grade got kind of saved on it. I feel like I should have done better for my efforts but oh well. Grade Distribution I got: - Chem Community: 100% (easy points) - Homework: 100% (also, easy points) - Test 1: 100% (I studied through the pre assignments he assigned over break, only had to review a bit to do well) - Midterm: 69% nice (STRAIGHT BS for this test, studied really hard on the new concepts... in the end it tested 1 problem from new content covered through class, the rest of the test was Test 1 content but more tricky, CHEM14A material, and THERE WAS NO FOLLOW THROUGH POINTS! Lost 16 points for messing up a calculation on Step 1 even though the concept was right) - Test 2: 96% (Studied my butt off for 2 days through homework problems) - Online Final: 100% (blessed that I went to every single lecture, took detailed notes, and had a ton of homework problems done that I can look at and refresh my memory when taking it online) I Took AP Chem and did really well on that in high school. You need to have a pretty solid understanding of the material to do well. Proceed with Caution but Lavelle is a great teacher and you certainly will learn a lot of Chem material from him! He does do a lot of things outside of lecture to give students resources to succeed, so if you enjoyed taking him with CHEM14A then you should still take him!
