<p>What formulas do they give you on the test? Is it clear what formulas we need to know? Where are some good places to practice?</p>
<p>They just give you basic geometry formulas that you should know without looking at the provided page (spheres, cones, prisms, etc.) You should be very familiar with conic sections and trigonometric functions (including as many identities you can remember, especially the Pythagorean Identities, but possibly including double-angle identities). SparkNotes provides pretty good free practice tests, with an online book to brush up on certain things. The SAT site also has 28 practice problems, with explanations and difficulty ratings.</p>
