Are the old GMAT official questions, review guide and Advanced guide questions along with official mocks sufficient to score 655?
Right now have taken 595 in first GMAT official mock and fairly I know the concept and I can answer >80% questions correct in review guides (Easy, medium , Hard level) with timer.
I'm a bit weak in DI where I need additional support on resources as well mainly with TPA and MSR sections.
Can someone help me with these queries?
