Is that what you are forced to use? How do you erase your writing--do you use a paper towel or something? Or do you need to ask for more laminated paper when you run out?
You will have 6 double-sides sheets of legal-size laminated paper. In my experience, that's more than enough for a single test section--which is fortunate, because the marker is wet-erase and can't really be wiped clean during the exam! In between each section, you should (and, from what I understand, must) turn in your notepad to get a clean one for the next part of the test. Most students will find this all the space for notes they need.
If you do run out of room, you can get a new one. Silently raise you hand--or, better yet, hold up your notebook--to get the test proctors attention. You'll likely lose 1-2 minutes off your test, which is less than ideal. However, it's quite manageable, if you just treat it exactly as if you spent too long on a single question. Look for opportunities to get back on track by taking a strategic guess or two on a high difficulty problem.
Good luck prepping, I hope this helps!
