I personally had 2 or 3 questions of trig on my test. Not just basic SOH-CAH-TOA stuff, but like in depth stuff that I haven't learned since 10th grade. Just make sure you brush over again and you'll do fine!
It was nothing harder than SAT math. There were no trig identities or anything. Just SOH-CAH-TOA for sine, cosine, and tangents. You should also know the two special triangles and their side lengths (45-45-90 and 30-60-90). 45-45-90 is leg-leg-leg*sqrt(2), and 30-60-90 is 1-sqrt(3)-2.
