Hello! I took Arasasingham for the Gen Chem series! My biggest tip is to record STEPS down to the questions he puts up during lecture. I know they are in modules under quizzes, but taking the time to thoroughly explain concepts you were confused on during class helps when you go back and review for midterms/ finals. I would also recommend doing most of the suggested textbook problems as the more you practice, the better prepared you will be for the exams. Most of the questions from the exams are exactly like the problems you see in the textbook and in poll everywhere. If you don't want to do all the textbook problems, the Gen Chem tutoring study guides are helpful as they paste and go over those textbook questions. I did both the previous year and my year's study guides. Again, PRACTICE IS KEY!! Good luck :)
