Hi leo,
Yes, I'm positive, if you studied under the *CBSE board* in India after 2004, you dont need to apply to the board for a verification certificate, you can take a printout of the webpage where your results are displayed online, have it attested by a gazetted officer and you can use that document as your marksheet verification certificate.. as I said, I just did this process two weeks ago and I've already received my Computer Number.
Please note this is only for people who did their 10+2 under CBSE board, the people I know who come from the ICSE and State boards have had to apply for their verification certificates to their respective board.
