I was wondering what type of questions are found here. Many scores have been low, is it because you guys don't have enough time or is it because you guys have never seen/study the questions. Were there a lot of surprises? What type of formulas should we remember. Did you guys encounter like surface areas or volumes of cones, pyramids or something? Should we just know the common ones like cylinder, sphere, or do we have to know everything? Also, for the trig part, are there any identities that we should know that are more complicated than sin^2x+cos^2x=1 and sin2x=2sinxcos ? How about parabolas, ellipses? Do you guys think the low scores are due to time or just not knowing the material? Thanks for the help.
