Hi kris,
Normally expire date of voucher is 1 year (except voucher for an assignment that have no expire date) and you must take an exam before expire date. If you purchase voucher on June 2007 the expire day may be 30 June 2008 (which is passed
) or you may lucky get the voucher that expire on 31 July 2008. I suggest
you should contact sun's training center to let them check expire date for you as fast as possible.
Wish you lucky.
