Great news and thanx.
I've had a look at the demo version and i must say its fabulous like the earlier versions of J@Whiz. The questions on new topics like Assertions, wrapper classes are really good and best part i liked was the detailed explanations.
But the Quiz should have the "Next" button.
Also I hope that their money back guarantee is applicable to this version as well. I should not be in a condition to avail it
