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

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.
