Thanks @"Seeking Perfection"! I retook in January and scored a 174, and I'm over the moon! I think I have a real shot at T14 schools, and a fair shot at T6 too! Maybe even a realistic shot at HYS?
That would really messed up if this rule ends up being retroactive. They can't change the rule in the middle of a race, it wouldn't be fair! I predict a bunch of people starting to take the GRE!
