Mathematics
1
Always read the directions on practice
tests.
• Do not waste time reading the directions on
the test day.
2
Math is 60 questions, 60 minutes.
• That’s one minute per question. ;)
3
Questions are not necessarily in order
of difficulty,
• But…... Questions from elementary or junior
high do come earlier.
4
Calculators can waste time
• The test was written to be taken without a
calculator.
• You can use one, however.
• The TI-84 is permitted.
• Most calculations are faster in your head than
with a calculator.
5
π
• Usually, when π is needed, the answers are
written in terms of π, so don’t use the π
button on the calculator and waste time
“undoing” it later.
6
The test make-up
• 24 Pre-Algebra and Elementary Algebra
questions
• 10 Intermediate Algebra questions
• 8 coordinate plane geometry questions
• 14 plane geometry questions
• 4 trigonometry questions (normally, 3 of the 4
can be solved using SOHCAHTOA)
7
Most people score between 17 and 23
• Which means you need to get 17 to 37
questions correct to be like “most people.”
8
Skip it!
• Skip questions that you absolutely do not
know. Work the ones that you can get right
first, to get more points quickly. Then go back
and work the ones you left out.
9
Order matters
• If you have no clue on a particular question,
and are forced to work backwards…..start with
the 3rd choice, and go up or down according to
how the answer fits the question.

• 1/3 of the questions require reading
something. (aka word probs)
