"the videos were interesting and informative however there was a vast difference between the level of the videos and the quizzes. it caused a lot of guessing and frustration because the questions and/or choices were unclear and the subject or topic being asked about were quite confusing.\nI am not completely sure that I have fully understood all the terms and concepts discussed. very frustrating."
