I took the GMAT today and scored a disappointing 620. Now I'm at a loss in regards to how to proceed from here. One possible way is to start practicing the GMAT Challenge questions (which are downloadable online after paying a fee. What do the people who have tried these challenges think of them? Are they very helpful?
Also, I've exhausted a lot of practice tests out there already including: Kaplan
Test 1 online and 5 Tests on CD, Princeton Review
Online Test, MGMAT Tests 1-5 Online, GMAT Prep Tests 1&2 and PowerPrep Tests 1&2. Did well in most tests but scored quite low on the actual GMAT.
Any ideas where/how I can get my hands on more tests?
