How would you, especially those who have appeared in exam, rate someone's GMAT prep based on following information? If someone has done all of the following?
1) All Manhattan 8 strategy guides
2) Manhattan 6 Exams
3) OG Guide 12th Ed
4) Gmatprep 2 exams
5) Kaplan free test
6) McGraw Hill 6 Tests
7) 800score 6 CAT exams
Anything else would you advice especially what to practice a week before the exam?
Thanks!
