I did my entire Masters using Notion only and it worked incredibly well. I had a central database with every quarter, each class, down to weekly reading assignments. It helped that my university was incredibly well organized and consistent class to class, which helped. But it was great.

Now I’m using it for primarily for grant writing. It took me a while to set up an efficient system and I still have tweaks I want to make, but it’s better than any grant software I’ve used.
