And good prep courses really do work. Tests, like coding interviews, are a game you can hack with enough time and effort. Years ago I took the GMAT and scored very highly, 98th percentile, and GMAT-taking is definitely a learnable skill in and of itself. Then again, maybe the test is really a proxy for “willing to do prep work upfront”. Having said that obviously it filters for those who have the opportunity to do so, but I am willing to give the benefit of the doubt and say the latter is not it’s deliberate intent.
