I love the idea of a bullet journal, but it has never worked for me. It's a combination of forgetting to use it and being afraid of messing it up, I think.
I use Google Calendar religiously. I have work, class, exams, study times, and personal events (doctor's appointments, movie showings, etc.) color-coded in different sub-calendars. I have the "agenda" view of my calendar on my phone's home screen.
I also have a spreadsheet that I add a page to each week with every item due that week next to its due date and weighted by importance. To the right, I have my raw percent complete and my weighted percent complete.
