Do you stay awake all night to do your revision?
And if you do,how do you do it?
^ lol haha
if you mean revision for the whole midnight, it would be utterly crazy. if you mean that you are inclined to get tired and your bedtime is very early ( 6pm - 9pm), maybe you can try drinking more coffee or redbull.. :/
I'm a night person, so I generally prefer doing revision at night. Many of my work is done during the wee hour. Night FTW!
