So I guess we are in agreement that studying only from the
OG is not the best way to get a great quant score? I just dont get why the questions in the
OG are so different from the ones on the test. Actually I can pretty much nail the first 100-150 questions on the
OG but the questions on the
OG diagnostic test are much harder?
So with these challenges, who writes the questions, and will I get practice in all aspects of the gmat such as percentages, probability, geometry and so on? Thanks!
The
OG is a collection of questions from tests that have been collected over 15 years. If you look at the 7th ed, the 8th ed, and the 9th ed, you will find about half the current problems. They added questions in the 10th ed, and then more in this version. The new ones are tougher than the others and more representative, but on the whole, the questions do not reflect the entire test.
But, on the whole, they do represent good marketing on the part of the GMAT folks.
