<p>I literally didn’t study for the december one lol, I am currently taking precalculus Honors as a junior and that might be the reason why. Thank god this test didn’t have so much for matrix and finding the middle term. Just to throw some tips, you should really master your calculator knowledge. Finding the maximum and minimum output of a certain function, even and odd function, basic trig rules like sin^2theta will definitely help you. Also, make sure to know your surface areas and volumes, because they love those questions. </p>
