Trust me when I say that especially the last week of studying, I felt like NONE of my study-days were effective/productive. I felt like I was actually learning less, possibly learning NEGATIVE amounts in the sense that I was cramming some trivial info into my brain and the outflow of info I thought I was forgetting exceeded what I was learning. I was a mess... I started to doubt myself and just think that I got lucky on a bunch of practices. I highly advise that you try to avoid this and keep a positive mindset. The truth of the matter is that you know a lot more than you think you know... it's like a reflex that you really are not fully conscious that you have - a knowledge that is attainable but that you don't realize in its entirety that you have. Keep pushing forward and think of each day, each hour, each minute, EACH SECOND, as an opportunity to learn something new. Stay positive and best of luck!
