Long school holidays could do you more harm than good, according to a report.
It found that being away from school for a long time can mean you start to forget what you've learnt during the school year.
Researchers say the school year should be split up into five eight-week terms, with only four weeks off for summer, instead of six weeks.
They think that way, you would be more likely to remember things you learnt in subjects like maths and science.
The study by the Institute for Public Policy Research also found that towards the end of the autumn term, which lasts 16 weeks, pupils and teachers get worn out.
The plan would mean you still get the same amount of holidays, but it would be in shorter chunks.
