I don’t think there is even an “appeals” process anymore. The best you can do is the score verification. There is another thread on it, but Josh also has a note in his TIA Blog:
“Since the exam questions and solutions will no longer be released, there will be no more appeals process for students to appeal their solutions as valid. There will be a scoring verification request for a $50 fee, but this will only confirm that your scores were recorded, and will not result a re-grading of your exam in any way.”
