Seems like you’re doing everything really well already. Keep it up. If you’re doing nothing this summer, look for a job.
As you travel, even locally, stop in at different campus types. A UW - big urban school. A small LAC like Puget Sound - which is in a larger city and more urban area. Then the opposite like a Whitman. And get up to Bellingham - go check out a mid size like WWU.
No need to formal tour - although you can (with an info session). Start to get an idea of the campus type, weather, environment that you like.
But you’re doing great - so keep up the great work.
PS - where will you take Calc BC if your school doesn’t offer it?
