I know during reading time, we are not allowed to touch our calculators or use a pen/pencil (nah, you sure gloamy?) but are we allowed to open our bound reference?
I think you can!
I didn't because reading time is where you look for the gift marks and where you will gain the most confidence.

How I tackled my exam 2 for methods and specialist was to leave the multiple choice to the end (MC accounts for about 20% and some questions can really bog you down)! In section B there may be some easy proof like prove "-" = "---", or given this function graph it over a < x < b, etc. Doing every easy thing first, hence, not doing the exam in the order given will allow you to feel much more confident when you look through and see in half the time you have clearly answered more than half the questions.
The bound book is something that you should refer to. Say you cannot remember for the life of you what cos(30) is, or some probability formula (probability was what annoyed me in methods), if a function is given to you to represent a discrete probability distribution, what do you do?
