I've bought SCJP voucher for which the validity is till September 16. The person from whom I bought the voucher says it can be used for either 1.5 or 1.6 .But I doubt.Can anyone tell me for which version is this voucher?
is it necessary to have any literal code on the voucher like 310-011?? i ve bought a voucher which doesn't have this literal. is something wrong with it?
