  2. Tips for taking the ACT Test • Pace yourself • Use calculator wisely • Use scratch paper given to solve problem • Locate the solution among the answers • Check if your answer is complete and then mark your answer • Make sure answer is reasonable • Check for your work

  3. Breakdown of ACT Math • Pre-algebra -23% • Elementary algebra - 17% • Intermediate algebra -15% • Coordinate geometry - 15% • Plane geometry - 23% • Trigonometry – 7%

  4. Pre-algebra • Fractions, decimals, square roots , factors , ratios, linear equations

  5. Sample problem 1 • Given the equation which of the following best represents y in terms of x? • Y =x/2 • Y = 2/x • y = x/16 • Y = /x
