Hey SDN, I'm planning on using Chads 2012 Organic Chemistry videos/outline/quizzes to prepare for the upcoming semester of Ochem. These are the College Chemestries, not Pre-Health/DAT. I was just wondering what sections of Chads I should review without touching material I would see in Ochem2. I'm not sure if I should do exactly half of the videos due to the fact I'm not sure if they're in a particular order. If it helps, the general topixs for first semester at my school are as followed.. Introductory organic chemistry: covalent bonding; organic nomenclature; sterochemistry; representative functional groups; molecules of biological importance such as alcohols, aldehydes, ketones, carboxylic acids, amines, carbohydrates. Tips for studying are always helpful & thanks in advance!
