AMEN!!I did 50-100/day. 100 was a lot for me -- it took me the entire morning (~4 hours) between doing the questions and reviewing, so I probably did 50 questions (as 1 block) most days. I studied for 3 weeks and only finished about half of the questions. It's ok not to finish all the questions -- they're just for practice and learning, it's not like there's a prize for finishing.
