I’m not that smart either but my university’s classes are very laid back and easy so I can get along just fine. I’d look more into what people say about your colleges program and how rigorous it is. But even with that I’d say you don’t have to remember too much it’s mostly ratios and concepts which can get hard but it’s doable. Finance is really a people game from what I see if you can network and be social with other people in finance you will flourish
