My gameplay advice is to not get too bogged down with the weekly stuff, it can get very tedious and pace-ruining (but can be interesting during some of the more major plot developments). If you get to a point where you just want to progress the main story and do some paralogues on the side you can automate that stuff, it won't massively affect your units gains if you're not running around the monastery every week so long as you're paying attention to what stats your students should be learning in their lessons for the classes you want to promote them to (and you'll get more than enough chances to raise support levels during main chapter maps and paralogues as well).

Oh and keep two saves after every chapter. You'll want to do that for this game as a habit, at least until later on.

And when you're done with Black Eagles I'd also suggest reading up on what happens in the other two routes. The routes themselves don't differ enough in terms of gameplay to merit playing each of them (unless you absolutely love the gameplay ofc then play em instead), but each of them illuminates some rather important world and plot information that either isn't emphasized or is outright not brought up in the others.
