I have the complete opposite issue.. what are you doing before you PT that keeps you alert/focused?
but in your case, identify your strengths and weaknesses and try to see any similarities. at times it could just be that the second LR was harder.
im not sure, i think its about keeping focus, but certainly knowing your strengths and weaknesses help. for ex when the 5m marker comes on and i only have like 6 questions left, i tackle the ones I'm better at first
I watch the explanations after my second run at the game, and almost as soon as i finish watching it i could grasp the concepts and get them 100% and at a reasonable time. I think i psyche myself out too much whenever i see a new game..
