Honestly... by the middle of the night you probably won't be able to focus, your work rate will plummet and you won't be able to sleep because of all the caffeine you've drunk, so... I would take Miracle Day's advice.
Even if you are hopped up on energy drink/coke/dextrose tablets, you will still have impaired cognitive function. The worst part is that you either sleep through the morning/early afternoon the following day (wasting most of the day), or wake yourself up early having little or no sleep (which is also pointless).
The best way, is to maximise how much revision you do in the day, without resorting to staying up when you should be asleep.

Oh that's where it's from. I've never watched inbetweeners lol
Anyway I already work through the day innit
There isn't much which will keep you awake and focused. Adequate amounts of sleep is generally more productive. As for things that will keep you awake and jittery, pro plus is often a winner. Or copious amounts of tea.
All nighters for upcoming deadlines are one thing, but for revision? Sorry, but that's just not a smart idea.
Go to sleep now, get up at 7. You'll get a lot more done tomorrow. If you try and do an all-nighter, you might be able to sit there staring at your page until morning, but you won't actually remember very much. Plus, you'll be too tired tomorrow to do anything, and you might well lose the day after as well as you ****ed up your sleep cycle.
Seriously, go to bed. Early. Then get up, early. Working 8am-11pm will be much better for your exam results.
