Good luck! Here are my test taking strategies. I've listened to other people but based mine on what worked for me in college.
1. Always sign up for afternoon exam slots (1:30pm for me). I'm not a morning person. I like to sleep late (10am), cook myself a good breakfast, and relax for a couple hours.
2. I wouldn't skip questions if I were you. I never flag them either. I always read each question twice before picking an answer – even for the easier ones. I think people waste more time skipping or flagging questions because once they go back to them, they have to reorient themselves with what the question is about. I can almost always narrow it down to 2 answers – I just go with my gut and move on. 1 MCQ is likely not going to make or break me, and I'd rather have enough time for the TBS's, which count much more.
3. Show up to Prometric early. Each time I show up at least 30 minutes earlier. Prometric has always let me start early too (I get the same amount of time in total).
4. Print an extra copy of your NTS and keep it in your car. This way if you leave the house and forget about it, you have your spare copy in the car.
5. Breaks – do what works best for you. Most people say don't take breaks because your clock still runs, but I think it's good to give yourself a breather – especially between testlet 3 and the WC's. You do have to watch the clock and make sure you are ahead of time though. I took a break between every testlet for AUD and REG, and I still finished both with an hour to spare.
6. RELAX! It's easier said than done. From reading this board, I think test anxiety plays a big part in whether or not people pass. I'm a big believer in self-visualization – I spend about 10 minutes in the car listening to some music on my phone that's upbeat and I imagine myself doing well and passing. I've even had the Prometric people comment on how usually the CPA exam takers are so strung out, but I'm chill like I'm about to go to sleep.
