Submitting assessments for your different classes are similar in their own ways but these are different because submitting assignments correlates to more of submitting your homework where as submitting assessments would be more of submitting tests, quizzes, or exams. To get started, locate the assessments tab towards the left side of the page. After clicking on assessments, you will see all current assessments and previous assessments. If you see a small clock icon next to the assessment name, that will mean that the assessment is timed and you will only have a certain amount of time to complete the assessment. 

To enter the assessment click on 'Start Assessment'. You will be taken to a confirmation screen to confirm that you would like to begin the assessment. After seeing this screen, click on 'Begin Timer and Proceed'. The full assessment will then be displayed and will include when exactly it will be due, how many points it is worth and will also display the set questions and answers that you are given to by your instructor. After you are completed with the assessment, click on 'Submit' to have the assignment sent off to your teacher. If the assessment is not timed then you may be able to click on 'Save' to save your progress and come back to work on it later.
