I have done Chad's twice and have attempted to go through Destroyer for this section but it's killing me. I find I forget stuff easily for this section, but I don't have much else to use to study. I bought Bootcamp but I would like to save those tests for when I feel I can actually make good use of them instead of making 17s on my first attempt. I would have bought QVault but it's so damn expensive now. Is buying just the G-Chem section worth it ($50) or are there better resources for G-Chem out there?
