At this point it may be good to focus mostly on #2, #3. For some of you, you should just mainly focus on #2, #3 at this point, to consolidate what you can do with the math you already have "learned".
]]>If you're in algebra 2, review inequalities, like AM-GM and such. Also do a lot of stuff with functions.
If you're in precalc, review trig identities. Euler's formula(e^pitheta = cos theta + i sin theta) may be very useful. Review functions + imaginary numbers + polar form too.

]]>To prepare, see if you can scoop up previous competition problems. Try to do these and TIME YOURSELF. also don't overwork yourself either.
If you have an extremely tedious problem in your hands, skip it first(if all of the problems are worth the same amount of points.)
don't stress!!
