It would be nice if we could retake quizzes for practice. It won't go towards our grade, but we can take the quiz just like normal as a way to study for tests. It could be an option that the professor can choose to enable.

Show the number of questions on online exams or quizzes so we know before starting about how long it might take.

When you finish an exam (with both multiple choice and written responces) it currently shows the score of multiple choice questions with the TOTAL number of points possible. This makes the score appear much lower because the written responses are not yet graded.
Allow the final score to appear such as : Multiple choice 37/40. Written responses ?/60 .
rather than currently: 37/100

When you complete submit an exam that allows multiple submissions it takes you back to the main exam page (with the "Start Exam Now" button). When you click to start it again you get a blank exam, so you either need to save your answers outside LS (generally a good idea anyway) or you start over. It would be nice to (1) see the answers you submitted after submitting the exam and (2) be able to see and edit your old answers when re-starting an exam.

On the "Exams" portion of a class, it'd be extremely helpful if next to close date or actions, there was a status table. Just a simple icon to indicate whether the exam was completed or if you still have to do it. This would be especially helpful since the grades page is so glitchy.
