I bought a voucher for SCJP from NIIT, Camac Street, Kolkata. There is no any hologram of Sun Microsystem(But of NIIT) and nothing tells that I am going to take SCJP 5 exam. They said that I could take any exam of Sun with that voucher. Is it okay?
Yes, that is ok and when you read it , it would say that you can give any Sun Educational Service Exam that prefix 310. Moreover there should be SUN logo marked on left top not as a hologram. That's what i have on mine
