Does your answer sheet for each part of the question have to go in part order (a,b,c,d). Lets say you didnt know part a and then moved on the part b, then later attempted a.
Does it matter?
Why don’t you just skip a page for part A, then if you come back to it you have it waiting for you rather than going out of order. These graders are humans, they won’t want to hunt around for the order of your answers. Hopefully you don’t run into not knowing how to do a question on the exam! Good luck!
I say go for it. If they can list answer orders:
A) Statement 1
B) Statement 3
C) Statement 2
Why can we answer B. E. A. D. C.
