# Frequently Asked Questions
To be honest, none of these questions have been asked yet, let alone *frequently*, but we expect they'll come up.
## How much work is this class?
ECER is a class of 5 EC, which corresponds to 140 hours of work total. That means that, in addition to attending lectures and tutorials, you should plan on spending an average of 12 hours per week on readings, homework, and assignments.
## Is attendance mandatory?
Attendance during lectures is voluntary but strongly advised. Participation in tutorials is obligatory. You may miss one session, but your tutorial instructor may ask you to complete an additional assignment to make up for the missed session. Students who miss more than one session without valid reasons will have a penalty of half a grade point applied to their final grade.
## Can I redo any of the assignments?
You can redo up to one assignment. To be considered for an improved grade, revised assignment need to be a noticeable improved on the original assignment and have to incorporate feedback provided on the first attempt. Revised assignments will be due within two weeks after the last assignment grades have been published.
## How should I format my assignments?
Assignments 1 and 3 should follow the Institute's Style Guide, employ consistent references, and include a list of works cited. Aim to write clear prose, and use paragraphs and subheadings to organize your writing. Use your creativity in assignment 2---no formal criteria apply (though you should still make sure to credit your sources!).
