OK, so my question in the title says it all. I am preparing to take the GMAT again and this time, I've changed my study philosophy. I have the Official guide 11
and 12 as well as the quant official guide
supplement and have spent the last 3 months really picking apart the questions. My goal in the quant is to be able to set the problems up in my head before I even write them down and solve them, which forces me to really understand the technique of solving the problem. On the quant, I am to the poi nt where I can solve most of the first 100+ DS and 200+ PS in my head. I am doing the questions, even the ones I know over and over...every now and then finding a nuance I missed before so I can really be comfortable with the question type when the test rolls around. I know I need more practice with sets and some number properties. For the verbal, I seem to be doing fine and if I usually get 90%+ of the questions right but the bold face ones I'm not too comfortable with. I am simultaneously doing the GMAT powerprep (the older version) and am saving the GMAT prep (newer version) exams for when I feel comfortable that I have reached an ability dictated score ceiling.
My question is this: If I completely master the Official guide questions and use other resources just as reference only to solve the OG questions, can I score a 760 (99%) on the exam. My last crack at the GMAT was a 720...which was a while ago, but I want to be a GMAT tutor, so a 99%tile or at least 98%tile would suffice. What are your thoughts about the theoretical "ceiling" of the GMAT official guide
? 720? 760? Could the guides lead one to an 800, or are there problem types the GMAT creators won't reveal so as to keep too many people from scoring an 800?
