I found morning lessons far more difficult than those in the afternoon. Scientists from Oxford University think that I might not be the only one.
Teenagers' body clocks could run three hours later than other people's, and the researchers think we should take this into account when setting school hours. Early starts could cause sleep deprivation and affect pupils' learning and health.
They've decided to recruit 100 schools and test whether starting lessons later improves performance. I'd try to be first on the list if I were still studying.
