<p>i’m signed up for Bio and Math IC but after reading many posts and hearing about the curve on Math IIC, i’m thinkin of taking that instead. Should i just drop Math Ic and take IIC or take both? and just how brutal is the curve for Bio/E? I heard it was really badd</p>
<p>Registering gives you a seat. On test day, you can do whatever you want and collegeboard will grade whichever tests you take. You can change tests, take extra tests, or only take one test. They will charge you for taking extra tests, but they won’t give you a refund if you take fewer than you signed up for.</p>
