I don't have advice that hasn't already been given, but seriously, DO NOT go with Kaplan unless you are really struggling with the basics. In my opinion, if you're willing to spend the money on Kaplan, you should upgrade your 7sage course instead.
It's OK. You're not alone. Have you canceled yet? Just take it one day at a time and maybe see about a different test center the next time if that's doable. And maybe upgrade to a course that allows more access.
