Exam Tips
Structured Programming
• You will be given several lines of pseudocode, and
asked to determine the final values of variables.
– Syntax similar to Matlab or Fortran.
• Need to understand logic for branching and looping.
–
–
–
–
–
IF/THEN
DO/WHILE
DO/UNTIL
FOR
GOTO (outdated)
• Could be asked about generic programming concepts.
Question #10
• A computer structured programming segment contains the following
program segment. What is the value of Y after the segment is executed?
Y = 4
B = 4
Y = 3*B – 6
IF Y > B THEN Y = B – 2
IF Y < B THEN Y = Y + 2
IF Y = B THEN Y = B + 2
(a) 2
(b) 6
(c) 8
(d) 12

• A computer structured programming segment contains the following
program segment. What is the value of Y after the segment is executed?
Y = 4

IF Y < B THEN Y
IF Y = B THEN Y

TRUE, SO Y = B-2 = 4-2 = 2
TRUE, SO Y = Y+2 = 2+2 = 4
TRUE, SO Y = B+2 = 4+2 = 6

Question #14
RESULT = TRUE
implies A.AND.B = TRUE
which requires that both
A and B be TRUE.
So A must be TRUE.
Question #15
• The following code segment is an example of
what programming technique?
b = cube(a)
cube(a)
{
b= a*a*a
return b
}
(a)

(d)
branching
function call
looping

Exam Tips
It’s a Marathon
• The exam is long:
– 6 hours total.
– Includes tutorial and 25 minute scheduled break.
– 5 hours and 20 minutes exam time (320 minutes).
• Think of it as a marathon, not a sprint.
– Develop your test stamina through practice.
– Get good night’s sleep: Don’t cram!
– Eat big breakfast. Bring a few snacks & a drink.
• Manage your time effectively.
– 110 questions  2.9 minutes/question
– Should use all of your available time.
Know the Handbook
• You will be given electronic access to the
“Supplied Handbook”.
• Know where to find things in the Handbook.
– Use the it when preparing/studying.
– The index can be helpful.
– the pdf is searchable, so practice doing keyword
searches.
Know Your Calculator
• Your calculator must be on the “approved list”.
– I recommend the Casio FX 115
• Take advantage of its advanced features.
– Integration, derivatives.
– Matrix/vector operations.
– Finding roots.
• Practice with your calculator.
– You can’t bring the instruction manual with you.
• There is an electronic backup calculator.
– TI-30XS
Passing Scores
•
•
•
•
NCEES does not release its minimum passing scores.
Your score will be psychometrically adjusted.
Passing scores have been between 50-70% in the past.
No penalty for guessing.
– Make sure to respond to every question.
– Suppose you only get 1/3 of the problems correct, and
guess on the rest. If 1/4 of those guesses are correct, what
will your overall score be?

æ 1 ö æ 2 öæ 1 ö 1
ç ÷ + ç ÷ç ÷ =
è 3 ø è 3 øè 4 ø 2
No Matter Your Discipline, You Can Get 1/3 Right!
Time Management
• Work the Exam in Three Passes.
1. Ones you know for sure, and can solve quickly.
•
•
Spend first 80 minutes answering the easiest 40 questions.
Per question: 2 minutes.
2. Ones you can likely solve, but will take time.
•
•
•
Spend 160 minutes answering 40 more questions.
Per question: 4 minutes.
Take your break an hour into this stage.
3. Ones you don’t know. Just guess.
•
•
Last 80 minutes can be for guessing, checking easy
answers, and attempting the very difficulty problems.
Should hopefully only have 30 such questions
Passing Rates
Conclusion
•
•
•
•
•
•
Approach the exam as if it were a marathon.
Know the Reference Manual.
Know your calculator.
Answer the easy questions first.
The computational tools section is one of the easiest.
You can pass!
