I found that when I tried to take tests without enough sleep I always
bombed, and that I did better with less cramming and sufficient sleep.
If you aren't deterred by that advice, use caffeine, but sparingly.  If
you get too hopped up you won't absorb anything you study and you run
the risk of precipitating cardiac arrythmias.  There is nothing safer.
And what are you doing reading netnews when you should be studying? :)

Cigarette smoking kills 1 in 5 Americans.  Almost half of those who
smoke die from it.  Even {*filter*} and {*filter*} aren't that bad for you.

Why on earth don't you just start studying a few hours sooner, enabling you to
take a break for sleep in the middle???? ()-:

Sorry to appear a Job's comforter, but you should not take stimulants to
facilitate last minute revision.  Quite apart from any other reason, all
stimulants in common use decrease concentration time; you may be able to stay
awake for hours or even days at a time, but it won't do you much good.  

If you must stay awake, caffeine (in tea or coffee) is probably the best option
since it has the least influence upon concentration time (so far as I
remember).  

Bear in mind that examiners are impressed by an integrated picture
demonstrating understanding of the subject; in my experience (as student and
examiner) cramming tends to result in a lot of half-remembered disconnected
facts.  Thus, if you are pressed for time, try to concentrate on principles
rather than the details of a recent paper.

Sorry if I sound pompous - most of us have been in your situation!

Caffeine, perhaps?  I always find a couple of litres of diet Coke keeps
me wide eyed for hours.  Guarana (guaranine - similar type of drug to
caffeine and theophylline) also perks me up, but without the hard edged
feeling that goes along with caffeine.
Sorry if this post is way too late.
BTW, sometimes a few hours of sleep make your answers comprehensible,
and are thus worth the missed study.

        Another couple to try, although harder to get, are DMAE
(dimethylaminoethanol) and phosphatidylcholine, both of which tend to act
as stimulants through the cholinergic portions of the nervous system (the
nicotinic receptors).
        Side effects of DMAE: Muscle tension (try upping Mg in your diet
if this is a problem), esp. if you're taking too much
        Side effects of phosphatidylcholine: increased sweating; increased
salivation; increased congestion
        Contraindications for either: Manic-depression; Depression; Asthma

        Neither of these, according to the studies I've seen, will
decrease concentration time. Indeed, some would tend to show them as
increasing attention (a smart-drug effect).

        Note: DMAE should not be taken by those with epilepsy, according
to some evidence.

        I would recommend L-Tyrosine instead, insofar as it requires less
conversion steps to get turned into catecholamines (epinepherine
(Adrenalin) and norepinepherine). I have primarily found it useful to take
when either of the following two things occurs:
        A. The caffeine isn't working anymore, and one is feeling somewhat
light-headed, etc. This indicates the stuff has depleted catecholamine
reserves.
        B. After a night of severe sleep-lack, unless one anticipates
several further such nights without sleep. I've found that about 5.5 grams
is what's best for me; your proper dosage may vary.

        One should keep in mind on either L-Phenylalanine or L-Tyrosine
that the body adjusts to a higher dosage via taking up less into the brain
after a couple of days (a sort of tolerance, as it were). Use either only
occassionally in order to get a full effect. Like L-Phenylalanine, I would
not recommend L-Tyrosine for someone with high {*filter*} pressure.

        Last week thewas a report on one of the TV news
magazines about simply using VERY bright light to stay awake.
The researchers claimed it was very effective.  It is likely
that this is just due to the suppression of melatonin production,
so light above ~2500 lux will work and a melatonin antagonist
may also be effective.  However, this may not be the mechanism
and a more psychological zeitgeber effect may also be at work.
Try putting 2r 3 florescent "shop lights" over your desk.

        Just to point out, caffeine works on adenosinergic systems,
not catecholaminerSince it blocks an inhibitory
neuromodulator which can decrease the release of several transmitters,
 could possibly increase catecholamine
release to the point where supplies are depleted, but I sure
wouldn't place any bets on this indirect mechanism.
But enough pharmacology trivia.

Or a couple of 500 watt floor-standing halogen lamps. Halogen
light doesn't make me as nervous as florescent light does.
