This is just my opinion, but really if you follow any program all the way through I feel like you will succeed. I tried the program on SDN (the one that combines TBR and EK), but it burned me out and a lot of the information I found to be superfluous. It wasn't until I did the online Kaplan videos that it really clicked and my score went up a TON. However, this could have been because I wasn't taking classes and because it was the second time around when I did the Kaplan. Every program has it's fair share of reviewers who scored really high 🙂
