CFAI practice problems vs blue box vs Schweser concept checkers

In these last 2 weeks I will redo as many mocks as i can. I’m also going to work in some practice problems, blue box questions or Schweser concept checkers. Which do you think are the best of these 3? Not long now until it is over…

I’d say past papers, followed by CFAI mocks, then online topic tests, then CFAI EOCs.

Don’t waste time practicing with anything else.
