Wo-o-ow! A 26 score – never heard of this before! Unbelievable!
My true story: I've signed, per an ill advice, for 3 exams in one testing window. And FAR was the 3rd one… I just didn't have any time to prepare for FAR, but didn't want to waste $200+, so I decided to get a “feeling” for this exam. That was the ONLY time when I felt relaxed & happy entering the Prometric test center :-))). I knew I was totally unprepared, so it was pure fun during those 4 hours. To my shock, I scored a 61 score. Probably, I was just lucky selecting the right answers. And I ran out of time, so I didn't touch the last simulation (back then, there were two of them), meaning that I missed the communication part too. So, a 61+10(communication missed)+ some 4 points for the 2nd missed SIM, and I might have had a chance at 75 without any prep. time. Big LOL!
I'm not saying that you can't pass 3 or 4 exams in one testing window: probably, if you study BEFORE applying for a NTS, then it's doable. But if you're just beginning to study and “stupidly” apply for a NTS for all parts, then you are doing yourself a big disservice. Imo.
I've seen this stats (for the previous 2010 exam format): you can get a perfect 99 for FAR, REG and AUD, but only 94 max. – for BEC.
