So I'm almost done completing the questions in the OG GMAT Review 11th edition. Can anyone clarify if the questions become more difficult as you go thru them? For instance, question 200 is more difficult than question 15.

I hope so because I am noticing as many correct as I was before. If so, if I am able to answer about 70% of the questions correctly does that mean I'm in about the 70 percentile.

Any explanation would be appreciated.

Most definitely. The later problems are generally more difficult than the earlier problems.

And no - the % you get right does not equal your percentile. You can get a bunch of questions wrong (no one's quite sure how many!) and still get 90th percentile plus, assuming the problems you get wrong are very difficult.
