Laugh now. Cry in the exam hall later. Then come back and do a past paper.

Revise all three sciences
Just revise the fun one
Me the night before the chemistry paper
Knowing it's three sciences
Knowing which teacher does which
Remembering which equations are given
Remembering which science you're actually sitting today
Science enlightenment, combined

Mum 💖

which science is it today? 🥰

all of them somehow

go on genius!!! 💪
