Agree on both points. I crammed a lot of grammar rules to improve my score, which was apparently was the thing I was missing to be a successful business person and totally not a classist barrier erected to exclude people without a private school education. This is the downside of any test that assumes aptitude means mimicking people who have already been successful in the field.
