I'd like your opinion, is this quiz actually doable or just a mean prank? How long do you think it would take to crack it manually? Any strategies? What is the least time a calculator could crack it?

I drew a mind map and worked out what the universally dependent questions are (questions which rely on you knowing all the answers already).

They are 1, 2, 5, 9, 12, 13, 15

Basically, what I'm trying to do now is create a calculator program which will run through possible answers and see if they fit the criteria. This cannot be done normally though, because then there would 4^15 loops. I've tried to reduce the workload on the calculator.

Let a = Q.5, b = Q.13, c = Q.7, d = Q.11, e = Q.6, f = Q.1, g = Q.2, h = Q.3, i = Q.15, j = Q.12, k = Q.10, L = Q.4, m = Q.9, n = Q.14, p = Q.8

Edit: I've finished my program!!!

With this many loops I hope the calculator will be able to solve the quiz within a few hours?
