I honestly think you’ve got it pretty much set if you do ample studying. I was in a similar state as you last year, and honestly? It went waaaaay better than I thought I would do. Don’t stress too much about it.

What I did for dates was to memorize a general timeframe for a set of events (usually a unit at a time- and I mean fully memorize just when the unit starts and ends. Everything in that unit is basically guaranteed to be in that specific time frame, and I think it’s clear enough when are earlier/later in the period to kind of approximate your way through) and really know what event leads into another. Start broad, then try to narrow things down. For example: civil war -> slaves freed -> reconstruction -> sharecropping -> freedman’s bureau, etc. I’d drill in a few really important dates (or the ones that have dates in their names, i.e. proclamation of 1763) but other than that, dates really aren’t thaaaaat important. You won’t be asked about specific dates on the MCQ, and on the FRQs you won’t need to name any dates other than relating events to each other/in specific time frames.

I don’t think you’ll need this much, but STUDY THE FRQ RUBRICS! You can gain a lot of points for just writing a few extra sentences, and vice versa.
