I have watched Chad's videos and taken notes on everything he says for all of them. I watched them over the span of 3 weeks. Then I started doing problems within DAT Destroyer and I am getting about 25% of the questions right. Should I continue doing problems and going over the answers in depth or should I re-watch Chad's videos until I feel comfortable enough to do Destroyer problems. I have about 6 weeks until my test and I want to make sure I am as prepared as possible.
