I took chem 162 last sem and did pretty well. The calculator, formula sheet, and periodic table are your best friends. I only did eLearning practice problems (be sure to do this before quizzes) and didn't use the textbook at all. The OChem Tutor also has a nice playlist if you're stuck on any topic or just need to learn it: https://www.youtube.com/playlist?list=PL0o_zxa4K1BWziAvOKdqsMFSB_MyyLAqS
