my favourite study method for consistency: the "study menu"

I don't know if this is a thing already, or if I came up with it, but my favourite way to study consistently is to create a "study menu". This "menu" has 3 "courses" or levels for different levels of energy. 1 is for high energy, 2 is for moderate energy and 3 is for low energy. I break my study sessions into 15-30 minute blocks for each subject with 5-10 minute breaks in between and pick 1-2 activities from the "menu" to do in that session. This prevents boredom and tailors my study to my energy levels so that I can stay consistent. I also like to have my "study menu" printed and easily accessible so that I can see all my options. Hope this helps! Let me know if you want any ideas for activities...
