Part I: What to Expect
SLIDE 4
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.

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 6
o Multiple-choice
o Read the question carefully
o Read all the answers
o Be sure you answer the question asked
o Check to see if your choice makes sense
o If not, check to see that you went through every step.
o Be sure answer is in the right units.
