Suggestion: Add check boxes

[shivasagarrao]

There should be following check boxes:

1. Display only Wrongly answered questions of selected subject(s)
2. Display only Unanswered questions of selected subject(s)
3. Display all questions(Should be checked by default) of selected subject(s)

If I select check box 1, it should only display wrongly answered questions of selected subject(s) which means if I select only 1 subject it should only display wrongly answered question(s) of that subject only not all subjects. With this option a user can easily see which questions he has wrongly answered.

If I select check box 2, it should only display unanswered questions of selected subject(s) which means if I select only 1 subject it should only display unanswered question(s) of that subject only not all subjects.

If I select check box 3, it should only display all questions of selected subject(s).
