<p>just in case, my calculator runs out of battery, I'm wondering whether is it allowed to bring 2 calculators to the exam?</p>
<p>Yes, you can bring 2 calcs, or extra batteries</p>
<p>:D that’s great!</p>
<p>According to Princeton Review, the magic formula requires that you bring 3 calculators. One plain, one scientific, one graphing.</p>
