The are two ways to get rid of exam fear ...and believe me they both work

:)

1)to prepare completely in advance,before the eve of the examination.

2)to not be bothered at all whether you pass or fail the examinations,and not be affected at all by the results.

you'd probably be better off with option 1. and even if you cant do this and you just start your studying a day before the exam(like me) then rather than studying perfectly, a section of your portions, i'd suggest you glance through your entire syllabus three to four times.you'll be surprised to know all the answers at the end of just three-four readings or glances..that way , you know a wider portion of whats likely to be asked , and thers more probability of asking questions ,whose answers you know.
