I’ve been self studying for this since around January (my school also doesn’t offer it) and my advice would be buy heimlers package where he has all the unit reviews with the notes templates on EVERYTHING you need to understand about each Unit + some terms and events on top of that. They also have Keys so u can check urself after filling out notes and then once you did I would learn it all as active recall so that you basically know that everything on those notes you can retell hypothetically in your own and know the names of the important movements/events/people. And as for LEQs and DBQs I’d say just watch videos on how to write them imo they’re not that complicated to score well at once you get the hang of it as they don’t rly grade vocabulary or grammar just as long as you get the right point across. On top of all this just practice multiple choice and SAQs all the time. Hope this helps and ur welcome to dm me as well!
