1 Nme Dte Advnced Alger & Trigonometry Midterm Review Pcket The Advnced Alger & Trigonometry midterm em will test your generl knowledge of the mteril we hve covered since the eginning of the school yer. SECTIONS AND SCORING Your midterm em will e roken down in to two sections. Prt (no clcultors: 0 multiple choice 0 points 6 openended 6 points Prt (clcultors: 0 multiple choice 0 points 6 openended 9 points Top score possile on the midterm 0 points PREPARATION The est wy to prepre for the midterm is to retke your old tests nd quizzes, focusing on ny questions you did not do correctly. In ddition, this pcket contins prctice questions (with nswers roken down y chpter. If you tke the time to prepre for this em, you my e plesntly surprised with how mny questions you re le to complete on the midterm.
