I think the consensus is that the newer ones are the better ones, so I would go with 13. I took 11 and 12 recently, and I thought 12 was more difficult.
Depends on the type of person you are, broseph. I can't speak for you, but I'm not the type of person to be easily discouraged. I have two practice exams lined up within a week of my test date. I'm going to use them to identify my weaknesses going into the exam, but other than that, I've done all I can - no sense in stressing out, IMO. Do your best. If you need to gauge where you're at, then take that last one and work on those weaknesses regardless of what you get. That's all you can do, bruh. Good luck. I haven't taken 13, so I can't comment on that.
