The more you keep learning while in a state of cognitive overload, the more chance you have at completely forgetting what you've learned.
Yeah!! this happened to me sometime back when I was preparing for a semester exam. I read for long hours so I could cover all the materials we were given. At the end of the day, I couldn't remember what I read in the first two pages of the note I was reading. I had forgotten a great deal of what I just read, but, subsequently I had to learn to read weeks before an exam to avoid stressing my self a day to the exam.
If you are like me and get worried that you'll forget something important. Spending an hour or two during your day of break to revise what you've learned could really help.
This advice will be very helpful. Hope to resume school soon, I will put that to use.
