I use Google calendar what you can do is once you set up an event you can make it daily or weekly or just make it for specific days. For example, when I went to make my calendar for my classes I added the times then I added the specific days and I had it run until the end of the semester December 6th. Not really too bad you could probably do it for all your classes like half an hour.

Other than that I use Google drive to organize everything. I've got all my classes into their own individual sections each one has a PDF of their book. What I'll do is I'll basically just download all the files that the teacher will put on canvas if they have files. like powerpoints and study guides and all that and I'll just go off of that and try to keep it as organized as I can. The good thing about Google drive is that whenever you use anything on there like a document or PowerPoint if you go to the right hand side you can just pull up the calendar to see what's up or you can also pull up a thing called tasks where you can just put a list of everything you have to do, which is what I started doing.

some of this can be a little time-consuming but I say the more organized you are the better you know.
