<p>I planned on taking the Math2 subject test on saturday. I just went through the book and realized I had not seen/knew how to do more than half of the practice problems. (I'm in a weird IB math class). Is there any way to switch tests or cancel only one test taken (I'm taking History, too). If it is possible to switch tests, is it a horrible idea to try to 'wing' the Literature Subject Test?</p>
