  1. IB Math Studies Test Taking Strategies

  2. Studying for the test. • Practice every test problem ever given to you! • Use the formula packet when practicing to familiarize yourself with where everything is located!

  3. Studying for the test. • Financial Math! For the "we buy “, "we sell" problem remember to use the rate for what the bank is doing. • Be careful of conversions! • Use: King Henry Died _ Drinking Chocolate Milk • Know what is contained in each of the number sets: reals, rationals, irrationals, integers and natural numbers.

  4. Studying for the test. • For chi-squared, if your value of chi-squared is greater than the CRITICAL VALUE you reject the null hypothesis. • For p-values, the opposite is true. If your p-value is less than the SIGNIFICANCE LEVEL, you reject the null hypothesis.

  5. Studying for the test. • Remember that a linear regression always goes through the mean point • The derivative is = 0 at a maximum or minimum!!!

  6. CALCULATOR DIRECTIONS • When using substitution into a formula, use ( ) around numerators/denominators • Make sure you can find the intersection of two graphs with the calculator • CALC (2nd TRACE  option 5) • Make sure you know how to find maxes and minimums using a calculator. • CALC (2nd TRACE  option 3 or 4)

  7. CALCULATOR DIRECTIONS • Make sure you know how to use the calculator stat functions. • STAT  Edit • STAT CALC  • 1-Var Stats for L1 • 2-Var Stats for L1 and L2 • LinReg for linear regression • Use linreg for ras well! • Know how to run the chi-squared test in the calculator. • MATRIX  Edit (put in table without totals) • STAT  TESTS  X2- Test…

  8. CALCULATOR DIRECTIONS • Normal Distribution functions! • DIST (2nd VARS) • normalcdf(lower, upper, mean, sd) • Use when given a % in the probelm: • invnorm(% to the left & out of % form, mean, sd)

  9. Before the test. • Sleep well the night before. • Eat breakfast. • Eat lunch. • Be hydrated, but not so much that you float away.

  10. During the test. • Your calculators have been cleaned out! • Make sure you are in degree mode. • Make sure your diagnostics are turned on.

  11. During the test. • Start each problem on a new page. • In Paper 1, always write the full answer before rounding in the working box. • Looking at point values…low point values on Paper 2 items imply use of the calculator.

  12. During the test. • If you don't know an equation/answer...make it up. Finish the problem using the made up equation. • Look at the problem: “Show that” means they want you to get that answer. And that answer will most likely be used in future parts.

  13. During the test. • Graphing: label the axes! • Make sure you know what a cm is on our graph paper. • Use the appropriate scale given in the problem. • Make sure you “show your work” on the graphs if you get information from the graph.

  14. During the test. • If you must draw a Venn Diagram remember to label the Universal Set! • Pace yourself! When you read the exam make a strategy for how you want to attack the problems.
