Don't worry, I just took a practice test last week and got a 410 and I'm almost finished with my MA! I think a lot of schools understand how hard the test is and take that into consideration.
My question for everyone on here would be about sending scores to universities where the subject test is optional. Most universities who say the test is optional say that they will consider the scores if sent, but it will not hurt the application. However, with a score in the 400s, would that be true? Anyone have any insight on this? I'm thinking about just saving my money and sending only to the universities that require it instead of sending it out with every application that I had previously planned.
