Here's your acceleration rate

One block per day in the beginning
Two blocks per day after a while
Three blocks per day when you are at maximum speed few weeks before the exam

Random, Timed, Unused, Full blocks

I agree with the rates given by Jajeek above.
Just want to emphasize that we are talking about random, timed, unused questions, and in full 48 questions per block.
