Store User Date EF MVC4 - asp.net-mvc-4

Question

Am trying to understand problem in how to store every user date like ( comments ,questions,....etc ) ... or when having list of requernmints and we need to store each user checklist of the requirement separately.... i though of the following example :
here an example :
I have list of Questions related to Subject. Then Student will be able to chose subject and view list of the question and answer them.
teacher then can come and see the questions answered for every students in separate view .
How to design the model and the view so that I will be able to store each student Answers!! so teacher can come then and see view students list under his subject and can chose a student to check his answer of the question....
Here my model classes and relations,I don't know the logic of design it .... please guide me!
I hope I explained well
