I had something similar happen to me before FAR with software issues. Basically, I was upset and wasn't even going to take FAR at all.
In terms of schedules, if you ask around, we all struggle with similar issues, I work full time, I have a kid who is in sports and training 3 nights out of the week plus practices and I'm getting married in 5 months. Life can get crazy and I think it's one of the constant struggles all humans have – HOW DO YOU FIND BALANCE IN LIFE? You've got work, family, studying, friends, personal time, it's unending. In my boat, my health has suffered since I've been taking the exams – I'm not exercising and my diet has gone to hell. I look flabby, I'm going to have a flabby CPA studying body for my wedding :'(
Anyway…Retake – close your eyes, take a couple deep breaths and thoughtfully consider each exam. You took AUD last. Would you rather pick up where you left off and keep studying for AUD? Do you think you could put in another 3 weeks and pull out a pass? Or, maybe REG would be better to take next because it's longer and you can get the longer one out of the way first. Make the decision and chose to stick with it because there is really no right answer to the question; what's right for you will be wrong for other people. Just decide what you're going to do an go balls to the wall with it.
Hang in there! The end is near. If you can wrap up these two exams in the next testing window, you'll be clear for the summer – and you should have enough time to do both retakes in the next window if you stay focused. You're so close so you know that you have a pretty good understanding of the material, you just need a little more to get you to the finish line. Think back to the exam – what parts had you completely stumped? Start there.
Good luck!
