The ACT Mathematics Test is a
60-question,
60-minute
test designed to measure the mathematical
skills students have typically acquired in
courses taken by the end of
11th grade
TI – 83’s and TI – 84’s allowed
InSpire 84 Faceplate ONLY
General Tips
• Answer the easy questions first
• Use logic on the more difficult
questions
• Answer every question!
• Review your work
• Be precise
• Erase completely
Test Tip
Watch your Time!
• If you run out of time, use the last three
minutes to bubble
• If you finish early, go back to difficult
problems and check your work
• Circle questions you want to come back to
