the delivery of the course was well presented and comprehensive however the questions or at least some of them in the "exam" were very ambiguous one example of this is the question which type of food is most susceptible to Bacterial infection the answer on your site is cooked beef burgers when in fact during the course it states undercooked burgers ie not cooked! I would suggest that these questions be more direct and obvious to anyone who has undertaken your course as many of the multiple choice questions displayed had more than one correct answer. other than that thank you.
