If you are really keen on staying with this great gal of yours,
I'd suggest you take control of the situation. Right now it sounds
like you're just getting dragged along.. and you might be
unwittingly be adding to her stress if she constantly has to worry
about you.
Give her more space. Work out the best plan to stay together..
be sincere, but don't make her feel obligated by sounding
desperate or pleading when you talk to her. Don't
pressurize her to meet up or call you/take your calls during the
exam periods.. Max u should do is SMS once or twice to wish her
luck before an exam, etc.. but if u're not sure what's acceptable,
ask her. Give yourselves a deadline for assessing the relationship
(an after exam date).
It can happen, but it depends on how you both handle it 
gd luck.
