From 1 June 2014, CASA will progressively be introducing some questions into exams which do not provide multiple choice answers. These questions will require only a numerical value(s) (no text or punctuation) to be entered using the keypad; e.g. 123. It is anticipated that these questions will be of a practical type such as, 'The distance from A to B in nm is closest to –' the candidate will then need to determine their answer and enter the value in the space provided. Where appropriate, CASA will set an acceptable range of values for the correct answer. The permissible range would vary with the complexity of the question, but would allow for variations candidates may obtain from using different methods or navigation computers.
