  1. Process of elimination
    Look for the following:

    1) Crazy Answers

    2) "Joe Bloggs" Answers

    3) Partial Answers
  2. Partial Answers
    1) Two seconds to reread the problem

    2) take a one or a few more steps to solve
  3. Crazy Answers
    1) common sense - take a step back and look at the answers

    2) typically can take out two
  4. "Joe Bloggs" answers
    1) attracted to easy solutions that can be arrived at one step or answers that repeat numbers from the problem

    2) eliminate one answer

    • Difficulty level (medim and difficult)
    • - Joe is attracted to easy solutions that can be solved in one step
    • - Joe is attracted to answer choices that simply repeat numbers from the problem
  5. Plugging In

    (Algebra)
    1) pick numbers from the variables in the problem

    2) using the numbers, find a target answer

    3) plug i the numbers into the answer choices to see which choice equals the answer

    Note: Game theory - during the beginning of the test, makes sense to check ALL the answers, but during the second half, go with the first answer that works

    • How to pick the answer:
    • Pick first answer (A) than the last answer (E), than B, D, C
  6. Types of problems to plug in
    1) Variables in the answer choices

    2) Percents in the answer choices (when they are % of some unspecified amount)

    3) Fractions or rations in the answer choices (when they are fractional or ratios of unspecified amount)
  7. Variables in the answer choices

    (Plug Ins)
    Main goal - find the final answer by breaking down each variable

    Then plug into each equation
  8. Numbers to plug in
    Keep it simple (small numbers)

    Unless it concerns hours and days, it make sense to use 24 or multiple of 24 (48)

    Minutes and hours - 60, or multiple of 60 (120)

    Don't use 0 or 1 = "weird numbers"
  9. Percents in the answers

    (Plug ins)
    Plug in 100 (convenient number)
  10. Fractions or Ratios
    Identify a specifc whole amount

    Number should be evenly divisible by 2, 3, or 5
  11. Plugging in the Answer Choice
    • This can be done as long as:
    • 1) The answer choices are numbers
    • 2) question is relatively straightforward (only ask for "what is x?", not "what is x+Y?")

    • Steps:
    • 1) Start with the middle answer (C)
    • - number answers are alwyas given in order of size
    • 2) If choice C is too small, try the next larger number
    • 3) If choice C is too big, try the next smaller number
  12. "Must be/could be/cannot be"

    (plug in)
    May need to plug in more than one number

    solve for x & y

    Go down the line

    Can also try 0 and 1 (weird numbers)
