Online Test Questions for Professional Certification and Academic Certification Examinations

Are answers referenced to published sources or are calculations shown?

When questions are graded, and the correct answer shown for incorrectly answered questions, a reference to a published source is not currently provided. Similarly for calculation type questions (such as noise and ventilation problems) the formulae and solution of the problem is not shown. This will be the subject of the second update of the CIH database which will start in June 2000 and be completed in the Fall of 2000.
