Great tips! As a current full time college student I think that all of these tips are quite useful. I would add take frequent breaks while studying! This helps to keep the mind fresh and avoids situations where you've read 6 pages and have no idea what's going on. I usually intersperse chores or art with studying. Study for 15-20 mins then load the dishwasher, do a quick sketch, go on steemit, anything to break up the monotony. After a break you return to your studies with a sharpened mind and more motivation!
