This speaks for itself.
At some point during the revision period you will get upset and you will want to give up. It’s totally normal to feel like this – I’ve had a massive meltdown at least once every single time I’ve had exams.
When this happens just PUT YOUR BOOKS AWAY and leave it for a few hours. If it’s late in the evening go to bed and sleep it off. If it’s during the day try and go for a walk, go see your friends or just watch Netflix for a few hours.
Taking a break isn’t giving up – it’s just taking a break – and it’s important you let yourself do it without feeling guilty.
