General exam advice: Don't try 2 learn anything new, but it is a good idea 2 skim thru ur notes 4 a lil while b4 ur exam.
Specific re: 2 exams on 1 day:
Do not try 2 remember anything 4 the other subject while u're skimming thru ur notes 4 ur 1st subject.
Pretend u have only 1 exam.
Once u've finished ur 1st exam, spend bout 5 mins talking bout it 2 get it off ur chest, then push it out of ur mind completely.
Eat, drink a *lil* and g2 toilet (in this time, wiping everything u no bout ur 1st subject out of ur head).
Skim thru ur 2nd exam's notes, or do woteva u do 2 get urself in the 'zone' 4 it.
It is more stressful having 2 exams on 1 day, particularly trying 2 balance ur study in the few days b4 them, but it is perfectly doable.
I had accounting and physics same day 4 mid-years, and legal and physics same day 4 end of years.
I was quite glad that legal was AFTER physics, bcoz the legal exam srsly fked my hand ova from all that speed-writing.
Make sure you sleep very well the night before. One exam is pretty tiring, two can really knock you out - but that's not until afterwards. During the actual exams you'll be running on adrenaline and shouldn't have too many problems.
Well-said, adrenaline actually comes in handy in situations other than u having 2 run fast.
