Need advice on skillset to develop before 2024 BB S&T internship

Hello, I'm an incoming 2024 S&T summer analyst at BB in NYC and I'm wondering if you could tell me the skills that I should focus on during my fall and spring semesters before the start of my 2024 internship. I'm from a non-target school that no one really cares about and I'm probs one of the few people from my college to get a Wall Street internship ever. I'm really nervous and I want to use that for good. I'm already working on getting used to Excel/PPT shortcuts. I'll learn Bloomberg Terminal once my school reopens (my school has it). I read WSJ every day to keep myself up to date with the market news. Thank you in advance!
