What do I do now?

Hey all, I recently was admitted to a top 10 target undergrad and I'm wondering where to go from here. I want to see myself working for a BB or an MBB in 4 years (I'd prefer consulting, but IB gets paid more and if I save correctly I might have $1m assets by 30), but I'm unsure of how to get here. In college, what classes do I take? How do I network well to set myself up for a possible future in consulting and banking? How do I make my CV as enticing as possible?

I've already managed to find a 2-year consecutive summer internship at a PE fund for this summer and last summer, and began to work on my skills as a prospective analyst through financial modeling courses and books like Next Generation Excel by Gottlieb. I will likely continue to run a charity organization I started in HS this summer as well (is this worth the time and energy?).

WSO please give me some tips as to where to go from here.
