Review notes and text - list
the major concepts and formulas that have been covered.
Highlight those topics/problems
that were emphasized. Note why they were emphasized.
The single best way to prepare
for problem-solving tests is to solve problems - lots of them.. Work problems not
previously assigned.
Analyze all problems you work:
What concepts, formulas, and
rules did I apply?
What methods did I use?
How did I begin?
Have I seen this problem before?
Is it similar or dissimilar to
other problems I've done?
How does my solution compare
with the examples from the book and class?
Could this problem be worked
another way? Can I simplify what I did?
In your own words, next to each
problem-solving step, explain what you did and why.
Look for fundamental problem
types. Usually a course has approximately 5 fundamental groups of problems - make
sure you can recognize what they are.
Practice working problems out
of sequence. For example, work a problem from Chapter 7, then one from Chapter 5,
then one from Chapter 10, etc. This randomness will allow you to see how different
problems relate to each other and will simulate the test-taking experience.
Work with a time limit - aim
to solve as many problems as you will have on the test within the test time limit
(i.e., 30 problems in 50 minutes).
Make up a practice test. Possibly
you might cut/paste/xerox a test from your homework problems.
Taking the test
Before starting the test, turn
it over and jot down all the formulas, relationships, definitions, etc., that you
are trying to keep current in memory.
Look the whole test over, skimming
the questions and developing a general plan for your work. If any thoughts come
to you immediately as you look at a problem, note these down in the margin.
Plan your time. Allow more time
for high point value problems: reserve time at the end of the period to review your
work and for emergencies.
Start with the easier problems,
the ones for which you can specify a solution method quickly. This will reduce anxiety
and facilitate clear thinking.
For the more difficult problems:
Make absolutely sure that you
understand the posed problem: mark key words, identify the givens and unknowns in
your own words, sketch a diagram or picture of the problem, anticipate the form
and characteristics of the solution (e.g., it has to be an integer, the solution
is an algebraic expression,etc.)
Make a note, in symbols, diagrams,
graphs or tables of all the information given.
For complex problems, list all
the formulas you consider might be relevant to the solution; then decide which you
will need to begin with.
If you have no solution method:
If possible, write out an equation
to express the relationships among all the givens and unknowns, accounting for all
the data and facts of the problem.
Think back to similar practice
problems to select a solution method.
Solve a simpler form of the problem
if dealing with complex configurations OR substitute simple numbers for unknowns
to reduce the amount of abstract thinking required.
Break the problem into a series
of smaller problems and work each part, thus building up to a solution.
Guess an answer and check it.
Possibly the checking process will suggest a solution method.
If all else fails, mark it to
come back to later and work another problem. You may find clues in subsequent problems.
For all problems, easy and difficult:
Once you have the solution method,
follow it carefully. Check each step for consistency in notation. Document all your
work so that it may be read easily, write legibly.
Evaluate your solutions. Check
your answer against the original problem to make sure it fits.
Try all test problems. If you
mind goes blank, relax for a moment and contemplate the problem OR mark it to come
back later to.
If you run out of time and still
have some problems left, try to gain at least partial credit by setting the problem
up in a solution plan (even if you can't follow through on calculations).
Analyzing the results
Read the comments and suggestions.
Locate the source of the test:
did the problems come from the lectures, textbook, or homework?>
Note any transformations - how
were the problems changed from those in the notes, text, and homework?
Detemine the source of your errors:
Were your errors due to carelessness?
For example, did you fail to carry a negative sign from one step to another?
Did you misread questions? For
example, did you fail to account for all the given data in your solution method?
Did you consistently miss the
same kind of problem?
Could you produce the formulas,
or did you remember them incorrectly?
Were you unable to finish the
test because you ran out of time?
Were you unable to solve problems
because you had not practiced doing similar ones?
Did you have a difficult time
during the test because you were too anxious to focus on the questions?
