revalidation of registration

@ surabhi - No, not needed in your case but still do it. you need to have valid registration at the time of filing exam form only and not at the time of declaration of results, but if you pass CA final exam in May 18 and you are applying for membership (in july / august) you must be a valid (registered) student of ICAI, without which you can not apply for membership. (your registration is expiring in june) Hence it is advisable to apply for revalidation now to avoid future problems.
