The official mocks have broken for me 3 times now in the middle of the test, 2 paid and 1 free, since the latest update. Is it just me or others are facing the issue too? While taking the tests, the prompt suddenly showed me something like "an error has occurred registering your request, please try again". On clicking okay, I was directed to the Practice test home page, and when I resumed, everything was awry. For example, in one of them, I had attempted about 18 questions but now it was showing 10/31 plus the timing was off too. I lodged a complaint with GMAC but haven't received any response; I don't know how they even can. I didn't finish the test after that - I didn't want to waste more questions.
So, yes! Wanted to know if I am the only one or others are facing it too. If yes, any solutions to try?
