Verify first that:
1 . . . your exam will be done on a modern $6000 computerized polygraph instrument, NOT on an old antique 'roll of chart paper with 4 pens'. You want the accuracy and sensitivity of a computerized instrument, and you want a computer to blindly score the test charts (you do not want a human to be doing the scoring, someone who can miss something or can be biased to be too easy or too hard).
2 . . . the accuser/client (spouse or victim) would be allowed, if desired, to quietly monitor the entire exam from an out-of-examinee's-view area or from a remote area.
3 . . . your examinee will be tested 3 times in a row, using standard 10-question charts (best for accuracy); with 25 seconds in between each question it means he/she will actually be 'on the polygraph' for 3 five-minute periods, with a short break in between each.
4 . . . you are permitted to arrive with the 4 key questions you would like to have asked during the exam. Have them written out, put plenty of thought into them. If you think that your situation needs more than 4 questions to cover it, speak to your examiner about this ahead of time.
Getting the truth for you
Polygraph is the world's most accurate lie-detection tool.
In virtually every city in the United States, you can not become a police officer without first passing a polygraph examination. Continual improvements in polygraph technique and instrumentation has increased the ability to pinpoint truth and lies better than just a decade ago.
But not all have the same training & experience.
