Afternoon slump advice

Basically didn’t go in today or Monday to study, as Fridays and Mondays haven’t much important classes

Anyway I usually spend most of the day studying if I’m not in school/the weekend

It all goes well from 9am to about 2pm, and after lunch I just can’t be bothered and feel so tired

Today I exercised and had a shower at 7pm to wake me up but I’m still half asleep

I need high points so I need to study more
