I solved all the 100 questions in my physics GRE on 27th October 2018. I am confident that I would have solved at least 90 questions correctly (I usually commit silly mistakes, so I would set an upper bound of 10 questions incorrect). Unfortunately, I could not keep track of time properly. I marked the answers to first 80 questions properly. Due to lack of time, I screwed up while marking the remaining 20 questions. Is there any way out of this? Will ETS check answers from my question booklet? (I have ticked the answers on my booklet).
Also, what is the expected range of raw scores to score 990 in the exam conducted on 27th October 2018?
