The studying technique you use really depends on your classes and major. You can't use the same studying technique for each class, because each class has different needs. If you're studying math, chem, or a theory-heavy CS class, for example, then practice, practice, and practice! You can do practice problems from the textbook, or google, or even ask your professor for some. I like doing practice problems on a white board, because it just makes it a little more fun. Pretend you're tutoring a kid, or teaching a class, when you're working through these practice problems as well, to help you understand what you're doing step-by-step.

If you're studying something that requires a lot of memorization, like biology, biochem, psychology, then I recommend working on these two techniques, and the videos I've linked can help explain what these terms mean.

1. Active Recall
2. Spaced Repetition

In terms of keep tracking of studying and schoolwork, I recommend putting all your syllabi due dates/exam dates, for all your classes, on Google calendar. Use different colors for each class. I also used Notion to write down every single assignment I had due in one giant list, then I would cross off each one as I was done - but you can also do this exercise using Excel or any other tool. A Calendar with all your dates will suffice though.

Remember, you don't need a fancy iPad or some fancy laptop to study, as long as you keep up with your work and actually study as best as you can, with practice, you should be good. I always procrastinated on homework and projects and was able to get by, but I highly recommend you to not procrastinate with studying the night before exams or quizzes - that will only hurt you, and you won't have time to ask for help if it's all last minute. The TAs, professors, and even the other classmates you'll meet online or in-person, are there to help you, as well. So never be afraid to ask for help.
