Based on everything I’ve heard about the testing of IT I would definitely suggest trying to get that percentage up. Probably focus on it and Corp gov for now and even out your percents some if you can but from what I know of it, those numbers look really good.
I started on Monday and after 600 questions am at the following for my test on the 9th. I think your scores are fine and that you should pass with those scores. I've scored above an 81 on my preceding 3 CPA exams and I don't think my trending has ever been higher than a 75% on Ninja. For AUD, it was literally a 68%.
