SAT II Math 2 with scientific calculator?

<p>I've taken the SAT II Math 2 test with a scientific calculator and I forgot what the tan, sin, and cos graphs looked like with all the funky transformations. I feel that the graphing calculator would be superior in this respect, so should I dish out the $100 to buy one? There's a clear advantage for the kids who use the graphing calculator (time and accuracy wise) and this kid keeps bragging about how he scored higher than me after using a graphing calculator. Any thoughts?</p>

<p>P.S.- Someone who takes the test with a graphing calculator has a better chance at getting an 800 than a dinky scientific calculator, right? (Assuming that this person knows his/her material) I read CB's site regarding this matter, and the test assumes that this person is using a graphing calculator. Ugh.. I wish I had one for the test.</p>
