Most Helpful Review
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!
