I took the computer-based exam and I highly recommend it because it follows how well you are doing. It gives you an easy question and when you get it right, it gives you a medium level one and then a hard one if you get it right. If you don’t, then it goes back to giving you a medium or easy one. Plus it’s easier in that you don’t deal with a classroom full of people and pencils and writing (here you just type). Plus the computer based exam is offered like every day whereas the paper based is offered like twice a year. Also you get your scores on the spot. I used the collegeboard CD they send you when you register as well as the REA CD which includes vocab builder games and practice tests.
