What are some tips on how to organize your study time?

Study for a period of between 20 and 40 minutes. You cannot concentrate for longer than this without a short break.

At the end of that time, stand up, do some deep breathing, and get a glass of water. It's not long enough to break your momentum but sufficient to refresh your enthusiasm. This is because an adult cannot maintain peak concentration for much longer than 40 minutes.

People naturally tend to remember beginnings and endings but lose the middle. By breaking up your sessions you will have more beginnings and endings than if you had one long slog over several hours.

You are also more inclined to remember what is unusual, funny, or sexy, so use exaggeration and humour whenever possible when visualising.

After your break, resume your study.
