During study time (those 2 or 3 hours a day), you have to take regular breaks to clear your mind and get strength for the next “round”.
Each hour, you can take a brief 5-minute break.
There are students who don’t make these brief stops, thinking they’re using most of their time wisely, but they don’t get what they expect. Without noticing, they start getting tired, and their performance decreases.
We need to use these brief breaks to go out of the room and stretch our legs.
We can do something relaxing (walking around the house, peeking through the window, chatting with a sibling or classmate, watering the plants, etc.), or something that demands low mental effort.
We need to avoid doing something we especially like (for example, watching part of a game that’s on TV), because then it would be difficult to go back to work.
The student has to be really strict about his breaks, not even going one minute over what was established.
If during the work session, you feel like you’re too tired, or you are not very efficient, it’s best to stop, even if you haven’t completed your study hours. If you feel fresher later, you can continue your work. But if you don’t, you can make up for the lost hours another day. You shouldn’t strain your mind.
