Hello,
Nis20. I know for a fact that you do not need to put in a stellar performance on Hard questions to cross the 700 threshold. In fact, I have helped many students achieve 730+ scores by advising them to
focus more on Easy and Medium questions. The GMAT™ is a test that punishes mistakes on lower-level questions more than it rewards accuracy on upper-level questions. In fact, I set up a tiered accuracy system for performance benchmarking that all but guarantees a 700+ score (provided you hit the benchmarks):
Easy—90 percent or greater
Medium—80 percent or greater
Hard—60 percent or greater
Basically, you are playing the probabilities that for a given type of question, you will succeed more often than not. By focusing on fundamentals, you will grow in confidence, and your performance will improve on harder questions as well. It is a win-win proposition.
Take some pressure off yourself. I sometimes even give my students one "free pass" for each cluster of five questions, a question they are allowed to guess on if it looks out of their depth. When you can break each section down into manageable chunks and give yourself a psychological edge in each mini-cluster of questions, you can put in your best performance.
Good luck with your studies.
