<p>I signed up for Math 1, but then realized that I'm actually capable of doing Math 2, so I plan to switch Math 1 for Math 2. How do I change subject tests on test day? Do I just bubble in Math 2 instead of Math 1 on the booklet on test day?</p>
<p>Yes. The test proctor will read instructions, if you’re still worried about it.</p>
<p>You can change, or add an additional test or two. (Up to mad 3). </p>
