error log from the above website and keep track of every question you do. I find myself learning a lot when I time myself for each question I do, whether it's from a book or from a practice test I'm reviewing. And then immediately after I do the question, while I still have the process fresh in my mind, I go ahead and review the answer explanation either from the book or from this website. The process does wonders. Sometimes I only get a few questions done (for quant) every morning while I study before work, but I can confidently say that whatever questions I do go over, I can grasp the concepts and apply them to other problems down the line. Plus it's a great way to stay organized and not have your brain so scattered.
