Hi friends, new ptdf oss scratch cards have been redistributed to head branches of first bank and state scholarship boards. I bought mine a few minutes ago from first bank. So if you are still interested, rush down to first bank or state board now because they have limited copies. I wish you good luck. AND PLEASE IF ANY ONE HAVE PTDF PAST QUESTIONS ON BIOFUEL PRODUCTION AND ENVIRONMENTAL ENGINEERING please kindly forward to me. My email ad is [email protected]. I will greatly appreciate it. Thank you.
