The main reason many students did not pass, or have an "E" grade, was not the exam, it was because their LMS Forum contributions were missing.
However, this is not bad news. It means you were not really ready for this course, and you can take it again next semester and learn a lot more. You WILL learn a lot more because your Journal work can be free choice, so you do not need to just repeat what you did this semester. Be HAPPY about this! A "Fail" is just a word, is does not define you, and it is a GOOD THING!
