My suggestion is to buy these tests either online or in hardcopy book format. The books are available at all leading bookstores, and some of them even have an accompanying CD-ROM for convenient printing of both questions and answer sheets. They aren't expensive either. I've seen Om Book Shop sell them for between Rs 1000 - 1500 a book, and sometimes they even have them on specials! Hope this helps!
