Have you already chosen your courses?
I'd pick subjects that are easy for you, for the first term, if you can.
It took me a couple of semesters to figure out my hacks - I made it way harder than it needed to be, initially.
Basically though, would say:
- stay on top of readings; do weekly reviews. Be as consistent as you can
- choose note-taking and organizational methods early, and stick with them (e.g., laptop vs handwritten notes; writing in the margins vs taking notes in a separate document).
What screwed me up for a bit initially was integrating the PowerPoint slides/handouts that everyone seems to use these days; I'm pretty old-school.
- plan/prioritize study/coursework backwards from due dates; weight assignments and study time according to percentage value of final grade
- give yourself more time than you think you need for exams. try to avoid cramming if you can
- expect to procrastinate, a bit, account for that too
- break study into 25 minute chunks - use a timer
- agree: don't let up on fitness activities - they'll help you think, feel, sleep, eat, digest better, making you a more effective robot
- caffeine
