Today and yesterday I worked on problems 1 to 396. I did OK for L10, but for L20, I forgot a lot of the problems.
I'm thinking about switching up the next 604 problems a bit ... I'm thinking maybe I should do some form of mini-circles ... such as this:
I'd continue to memorize chunks of 20 and then work my way up to a chunk of 100 problems. Once I get to the 100th problem, I'd review that set 6 more times. So I'd do 7 mini-circles for each 100 problem set until I finish the 1000th problem. Also I wouldn't go back to review as often, if at all. I'd just focus on the 100 problem chunk and then move on to the next 100 problems without going back to review previous chunks.
