  • Acs Instrumental Analysis Exam Questions

    Each question is shown with four possible answers, only one of which is the correct or best answer. Unscored questions are not identified and are randomly distributed throughout the exam. These items are not identified for examination candidates at the time of testing. This is standard practice and enables CCI to evaluate questions which may be used in future examinations. These items are not scored when your examination results are calculated and thus will not affect your score. Two hours and fifty 50 minutes are allotted for answering the exam questions and ten 10 minutes are allotted for a tutorial and post-exam survey. The time you have been allotted to take the examination has been determined by taking into consideration the number of scored and un-scored items.
