4: don't forget to shower. Please. Jokes aside, it is really unhealthy and disturbing for others.. let's revolutionize the buzzkill stinking alt-right "incel" tech guy stereotype by starting to shower once in two days!

3: try to avoid mac-books. I know they look fancy and you can use the "bash" terminal, but you will suffer a lot from trying to download the weird applications your professor demands to finish the assignments. You'll probably boot (or dual-boot) a Linux distro anyway, which contains various choices.

2: try to choose a laptop with a good battery life, lst. like at least 10 hours. Don't forget that because you'll probably spend most of your time in the campus, so you will not enjoy to carry the battery with you (again, gaming computers are famous for usually having a poor battery life).
