I've been studying on and off for about a year (with big breaks because of school, work, etc.). I've been pretty consistently scoring in the high 160s but really want to be 170+ (at least) on the actual test. I was planning on taking the test in September after an advanced course in August. The deadline to register is the end of this week. However, I feel nervous signing up for it unless I'm already scoring in my goal range, as I've had to back out before and lost a lot of money. I also want to apply during this application cycle and know it's better to get apps in as early as possible. Should I take a risk and sign up for the September one or push it to October??
