I found this website just a few weeks before I took the GMAT. Here is my big problem. I went thru all questions on ETS and take Arco cat test 5 times just a week before the final GMAT day. All the while I got 580-600 on all 5 Arco test. On GMAT I score only 400 something, not ot mention my greatest shock. Is there anyway I can improve my score ? I was completely depressed after my exam. Some ppl have told me that Arco predicts pretty close but it prove wrong to me. But my quesion now is how I can improve ? I think I want to re-take the test in 7 weeks time. By the way what is "OG" that ppl are refering to in their post ?
Wing, I would also get some Kaplan materials.
I believe the forum here generally agrees that Baron's and Arco are not the finest and most essential materials.
The best predictor for the test is PP (powerprep) the software released by ETS.
The reason ARCO gave you 200+ points above your final score is that the question difficulty is different and scoring algorithms are not the same either. ETS keeps their methodology secret and no prpe company can or may replicate it. I would stick to the generally acknowledged materials - OG, Kaplan, PR, PP.
