ST. MARK’S MATH PLACEMENT Dear new St. Marker, Welcome! In order to find the most appropriate math placement for you, I need you to take the enclosed placement test. This test is meant to be taken by students coming from a variety of backgrounds, so answer the questions that you can, and show your work on everything, so that I can see your reasoning. Please mail your completed placement test to the Admissions Office by May 19, 2016. The course usual course progression through Precalculus is as diagrammed below. Usually after Precalculus, students select from Calculus and other theoretical mathematical courses, or applied mathematics courses such as Mathematical Modeling and Advanced Statistics. Precalculus Algebra II Geometry Algebra I Directions The attached placement test will be used as one factor in helping us to judge your appropriate math placement. • • • • Please take the test without help from anyone. Show your answers and your work on the test paper or on attached paper. Be sure your name is on all sheets of paper that you return. Please take your time – there is no time limit! If you have completed (or are currently taking)… …then complete the following sections. Pre-Algebra Pre-Algebra Section Algebra I Algebra I Section Geometry Algebra I and Geometry Sections Algebra II and beyond Algebra I, Geometry and Algebra II Sections There may be problems on the placement test that touch on unfamiliar material. Do your best to solve the problems correctly, take your time, and show all your work clearly. If your work on this test and your previous work in mathematics indicate that you are a candidate for an Honors class in the fall, I will notify you about taking an additional Honors Placement Test, which will be given during orientation. Thank you, Allyson Brown, Mathematics Dept. Chair [email protected] ST. MARK’S MATH PLACEMENT PRE-ALGEBRA SECTION Complete this section only if you have not taken Algebra I.
