Quick update in relation to my review of Simple's new revitalising eye roll-on. I forgot to add that products like these aren't the only solution to the hang-ups of exam stress!
Make sure you drink plenty of water, take short breaks away from computer screens, eat properly, and try to get around 6-7 hours sleep a night if you can. (The 8 hours thing is a fallacy: studies have shown that the body needs around 6-7 hours a night to maximise life-span and improve daily functioning. Any more or less actually has negative consequences in the long-run.)
