Is it possible to be busy during the break? It's absolutely possible to be very busy during the break because if one is doing something very urgent, she/he has to spend time working on it during the break. Then she/he will be very busy. But usually I prefer studying non-stop for like two hours and have a little break. I believe just like muscles needs a break after an intense exercise, the brain also needs to take a rest. I prefer a long break more than multiple short breaks througout a day, because I'm used to concentrating on one task at one time and I don't want to be disturbed by those short breaks or any other things. Have you ever studied science? I have studied science in college. We had courses of Advanced Maths, College Physics, etc. I love science because it's a good combination of natural regulation and logical analysis.
