ramdhaan fast

Not fasting in the month of Ramadhaan due to exams

Q: I am a student in Saudi Arabia studying in a private school in Dammam. Our school recently changed their examination dates. The problem is that Ramadhaan is during these days.

My question is that is it permissible for a student to skip 2 or 3 days of fasting for exams? I might not be able to concentrate on an empty stomach during the exam and while studying for it.
