Point me in the right direction for the industry/beyond?

Hi, incoming freshie at a target and getting the feeling that I got in on a whim and I'm in way over my head with how talented my classmates seem to be. Used to indulge in stocks and options heavily earlier in high school before classes and apps season kicked into high gear so I kinda lost touch. I'm looking for pointers on resources and topics I should be taking apart this summer to become grow professionally. I've been meaning to gun for IB for a while now and am somewhat familiar with how recruiting works. I'm more interested in specific topics I can research and read about in my free time and someone to point me in the right direction.

Before anyone says to go out and live life, have fun, etc... don't worry I'm not a fucking robot lol I feel like I already do all that enough. Some of the things I'm already looking into are different valuation models and Excel practice. I would also welcome topics pertaining to the finance industry as a whole rather than just IB. Subjects I'm interested in learning about are stock pitches and analysis.

Again, any advice would be greatly, greatly appreciated. English is not my first language sorry.
