TSIA Test Prep Luis Molina John Cox SLIDE 1 Agenda Part I: What to Expect o Texas Success Initiative o Tips for computer based testing Part II: Test Section o Math SLIDE 2 Part I: What to Expect SLIDE 3 Texas Success Initiative o TSI tries to give you the best starting place. o Goal is to place “at” not “out” o Tests your knowledge of concepts you may have not seen in a while. o Mathematics section tests you for Algebra o If the assessment sees fit, it may test further. SLIDE 4 Tips for Computer Based Testing o Read it twice, slowly. Three readings are good for word problems. o First time, get a feel for the problem. o Second reading, get a grasp on what is given and what you need to solve for. o Third, predetermine the steps needed to solve. o Use your scratch paper. Bring plenty of it. SLIDE 5 Tips for Computer Based Testing o Multiple-choice o o o o o o Read the question carefully Read all the answers Be sure you answer the question asked Check to see if your choice makes sense If not, check to see that you went through every step. Be sure answer is in the right units.
