1. Eventually assignments need to be available in the student interface so the students can complete them, however, the functionality/interface of completing an assignment is different from creating, viewing, or editing an assignment. In this homework you do not need to implement that.

2. As I said several times, viewing an assignment and editing an assignment are two different functionality, so you must implement them using two different controllers/views (though they may share very similar code). In this homework you do not need to implement assignment editing.

3. Again, you do not need to implement editing in this homework.

4. You need to do better than current CSNS UI to get extra credit. Also note that a) it's "up to 20%", not 20%, and b) "better" does not necessarily mean "fancier". In particular, a well-designed UI should require the least amount of effort from the users to understand it and to use it, i.e. the users should not need to read a manual to figure out the UI, and performing an operation should require as few mouse clicks and/or key strokes as possible.
