Hi jonmarrow,
At this point in your studies, you likely have very specific areas/concepts that you need to work on, so it would help to know how you perform on a realistic, FULL-LENGTH CAT (with the Essay and IR sections). With that score result, we'd have a much better idea of what you should be focusing on (and the types of resources that would benefit you), as opposed to just trying to broadly cover a lot of different subjects in these last few weeks. Whether your studies are 'normal' or not shouldn't be a concern at this point - your specific goals might require an atypical approach. I suggest that you take a new FULL-LENGTH CAT sometime soon and report back here with your scores. We can then talk about how best to proceed.
