I had rarely used a tomato clock before and felt it didn't do much for me, 25 minutes for things I liked to do wasn't enough, 1 minute for things I didn't like to touch, and I was confident that long periods of concentration were not a problem. But there is always an intermediate situation - "something you don't like, but have to do" - and this is the right situation for a tomato clock. When this happens, 25 minutes a tomato, rest immediately when the point is reached, not long after, to restore the mood and promote the achievement of the goal. Classmates who like it can try it.
