Since I am moving forward to study into two masters programs. One particular studying technique that I recently learn take up between 30 sec to 1 min. Simply pick a particular section of the subject you’re learning and list out all the facts and concept associating with it. Once you have that, build on it and list out more. Then, you will ask that same question again the next day and see if you can repeat all the answer. Repeat until you get it 100%. Once you got that, erase and move on to the next section.
This particular technique is use to remember a lot of different types of information (or definitions). Test that are concept or solving problem doesn’t work.
