Your Mobius assignment marks are automatically sent to your LEARN course gradebook. If you complete an assignment several times, your Best mark for the assignment will be in your LEARN gradebook.
Mobius too has a gradebook. By using the Gradebook link on your Mobius page and then selecting View Past Results a list of completed assignments and lessons with their scores is presented.
Under the Feedback link more details are given: your response, the correct answer, the score for each question and if available, a complete solution.
If Feedback for an assignment is turned off for a period of time then the Feedback link appears as a lock icon.
Note that every assignment attempt is listed and dated so you may see several lines with the same assignment name but different dates. Sorry to say, the date time is given as GMT not EST time so subtract 4-5 hours.
