Complex, Life, and Psat: GUESSING STRATEGIES
Use the following strategies as a basis for guessing on problems you don't
how to solve.
Rule 1
When you have no idea of the correct answer, choose the one has
that most in common with the other answers.
choose (B): Four of the answers have v3. four divide by 2 and four
are positive.
Rule 2
Avoid guessing the same letter answer as the letter chosen immediately
before. Out of 165 questions, there were three instances of the same letter
answer repeated 3 times in a row and there were no instances of the same letter
answer repeated 4 times in a row.
Rule 3
Avoid choosing non answers such as "All of the above" or "None of the
above" when guessing on questions with 5 answer choices. Only select this type
of answer if you know that it is correct. out of 165 questions, these answers
were correct only twice.
Rule 4
don't when asked for the smallest number of things that meet a certain greatest
choose the smallest answer when guessing. When asked for the number, don't choose the greatest answer when guessing.

Example
In the figure above, if AB

20 and the area of
ADC 240, what is the area of polygon ABCD?
(A) 420 (B) 480 (c) 540 (D) 5
(E) 680
Guess C or D
Rule 9
Substitute whole numbers that meet the criteria, for variables in
problems. The operation for solving with whole numbers is the same opera
you would use to solve algebraically.
Example
If a man will be x years old y years from now, how old
years ago?
(A) x y z (B) x-y+ z (C) x+ y 2
(D) x -y z (E) -x y z
Substitute whole n
40, y 10, z. 5. Then the problem becomes.
man will be 40 years old 10 years from now, how old was he years ago
5 man will be 40 in 10 years, he is 30 today (40 The
years old 5 years ago. (40 10 5 25). This corresponds to
correct answer is (D).

Rule 5
If four relatively simple appear with a very complex fifth choice,
answers avoid the complex answer when guessing.
Example:
Eliminate (E)
Rule 6
When you don't know how to solve a problem algebraically, work backwards
and plug in answer choices.
x 7x 12
Example.
If (x 4)
5, then r
(A) 1
(B) 2
(D) 5
(E) 6
Start in the middle, if that answer is too big, go down to B then A. lf
too small, go up to C or D. That way you'll only have to test 3 answers
at most.
Rule 7
On harder math problems, don't guess answers that just seem to go.
Example: Five people go to a photographer to have a group picture
taken. How many ways could the five be arranged in a
straight line for the picture?
(A) 25
(B) 30
(C) 60
(D) 90 E) 120
