I subscribed about a week ago. So far I am about 60% finished with the questions. Here goes...
Pros: Questions are on a lot of the topics I remember seing on last year's test, extensive explanations with references, charting by suject and exams, computer-based, good images.
Cons: Only 260 questons, few early glitches in the testing system. Little feedback from others who have used the product.
Overall: Very impressive. Questions and explanations are much better than Hall. There were a couple glitches in the OB section when I signed up but I emailed them and they fixed everything right away. Still new though so I guess we'll have to wait and see. Any others wanna comment?
