Hey! So, I'm starting university this year, going in for a BSc. Physics and Astronomy, and one of my first year courses is computer science for the physical sciences. I do have some coding experience but it's very minimal with html and and Visual Basic, not very good languages. I did well in grade 11 computer science but I need a refresher, and perhaps something that'll let me get ahead. Are there any sites anyone can share that may help me? I don't exactly want to use code.org but I am, along with code academy. Is there anything else?
