When to start aamc materials?

I'm taking the test March 31st, so just wanted an idea of when people started to use section banks/qbanks/other things, since I don't want to start them too early (but also not too late). I was thinking doing the OG questions the end of this month, and starting qbanks and section packs around feb 10th ish. Is there a plan that most people follow? Thanks so much!
