Two down, one to go.
The 86, while it only has 150 questions (as opposed to the Series 7's 250 questions), actually took longer than the 7 to finish. That's because you actually have to calculate numbers and think about the questions, unlike the 7, which is essentially a 1930s vocabulary test. A friend of mine suggested that the number of the exam is actually the last year in which the subject matter was relevant.
I was actually a little worried about this one, since I was scoring in the low 70s on the practice exams, with my own calculator and all the coffee I could want. Turns out the practice exams are harder than the real thing.
