Learning how to model companies from scratch

Hey guys, I just secured a return offer and I’m hype. I’ll be returning to school for my last year and want to take time to teach myself how to build models from scratch. I think it would help develop my understanding of a lot of useful stuff. The return offer is for a job where I will be working with all asset classes but do y’all think taking the time to learn how to model public companies is a good idea?
