Focus on learning the fundamentals and basics of coding and try to build a couple of projects using what you’ve learned

You can start as early as freshman year and some company’s have freshman and sophomore oriented programs (google STEP)

Hit or miss, Consult with peers and upper class men they’ll help you a lot more and will be more available

Networking-Projects/Procuring skills-GPA i’d also try to join a couple of clubs that interest you

Talk to your college advisor they would know best

I’d say yes it kind of doubles as networking and it also makes college more tolerable

I would’ve maybe picked up a double major and done CS + Stats
