User 1:
1. Liked the idea and thinks the MVP is a good start.
2. Did not like the navigation and thinks it should be improved.
3. Believes there should be better ways to go back to classes/students once one is created or changed.
4. Did not like the layout of classes/.
5. Most of the views don't have a means of emptying out/resetting after action is taken.

User 2:
1. Excited to see graphs in later version.
2. Did not like navigation in general (like User 1).
3. Found bug: can enter exact same student multiple times in same class. Need to keep that from happening.
4. Pointed out that no student grades shows up as NaN. Also wants to see the titles for each key in class and student objects capitalized and polished up.
Otherwise same as User 1.

User 3:
1. Wants ways to sort information better especially for when the list of classes/students gets big. Eventually wants to be able to sort by grades too.
2. Really wants to see the grades portion of the app get implemented and suggests having a bulk way to put in grades and thinks that doing it one-by-one should be avoided. In other words, he wants a way to be able to update students' grades for a given assignment/exam.
3. Overall likes the idea of the app but finds implementation clunky for similar reasons as Users 1 and 2.
Note - might even want to see a bulk way to add students if possible.
