I tried to re-register multiple times today and kept getting the “all sections of the exam are in progress.” I just received my score and passed, so it seemed to work for me.
If Result Watch says you passed, you passed. CONGRATULATIONS!!!! It pulls directly from the NASBA site and I've used it for 3 of 4 exams and it's always accurate. Time to celebrate! I take REG on Saturday and it's hopefully my last one too. Good luck!
