<p>These are more exam-related than problem-related, but...</p>
<p>a) I know it says we are allowed to bring two calculators but are we allowed to use both at the same time? I'm mainly using a TI-84 but I thought I'd bring my TI-89 just in case I go brain-dead and need to factor something quickly.</p>
<p>b) Since it says you don't have to clear your memory, are you allowed to write down formulas and such on Part A of the free response (the calculator section) and then use these on Part B of the free response (non-calculator) since you will still have your Part A packet during this time?</p>
<p>Thanks.</p>
