Scholaranium is an excellent addition to the e-gmat course. I like that you can track what you’re getting wrong and what your weak areas are. If you’re working a lot, one of the biggest constraints is time (even more than money frankly) and it’s better to spend your time on areas that need improvement in a targeted manner as opposed to flying blind and trying to do everything.

I'm glad I signed up for the course and recommend it to people who don't have much time to crank out a good score. My only criticism is there aren't enough questions in the CR section but in general I've noticed good GMAT questions are hard to come by. Either way, highly recommended.
