Knewton 590 --> 710

When I took my first GMAT in January I only scored 590 (Q38, V 33). Although I studied for several months I failed to recognize the importance of really understanding the concepts behind the quant and verbal sessions.
I desperately needed to get more than 600 points to apply for my favorite business school. The 50 points-increase-guarantee was just perfect: Either I will reach my target score, or I will get my money back.
The course was really good, although sometimes really demanding. My first practice tests (550, 600, 570) weren't too good either and I sometimes almost lost the confidence in myself.
But once the 13th and final class had passed I scored 640, 650 and 700 on my last 3 Knewton CATs. My GMAT Prep scores were 680 and 690 - several paper based tests were also in the same range.
When taking the exam I could really apply all the different skills I've learnt during the Knewton classes - I felt really confident when answering the questions, that I finished really early (the first test taker in my test center) and I was really eager to finally see my score: 710 (Q49, V 38) - I was really amazed by this 120 points increase. At most I was hoping for a score within the upper 600s. Honestly, I can only recommend Knewton to test takers who really want to improve their score, want to put a lot of effort into it and want to work on their GMAT concept skills.
Thanks a lot Knewton!
