Scratch paper and Prep Course

Hey all, 1.) I am guessing we wont have scratch paper during test day, but will there be a lot of space between problems for us to do our calculations? 2.) I see A LOT of posts about Schweser especially their Qbank. I took Stalla, and I am using their Passmaster program. In case I fail this time around, I will probably purchase the Q-Bank for extra practice. But are the difference between the two programs marginal or very significant? Thankss\
