9th Grade SHSAT Focus?

Question

I am planning to retake the SHSAT and sign up to take it in November. I wanted to know if there are any other topics besides trigonometry that are worth studying. Like geometry or algebra? Also, I know that the scale scores are not proportional to raw scores but I was wondering that if scoring in the high 40's in the Mathematics and Reading sections would help me gain admission to Brooklyn Tech for the 10th grade. Any help on this would appreciated. Thanks in advance.
