[Fullstack] Testing and Finalizing

## Context

We want to make sure everything in the app works as expected.

## Requirements

### Task 1
When creating an account and choosing a chapter, there should be white space that pops up at the bottom of the screen so the user can see what they are entering into the dropdown.

### Task 2
Sometimes in the same screen, the screen is very shaky and does not work completely properly. Additionally when typing numbers, the only way to exit is to go onto a different screen and hit return. See if you can add a way to exit from the number pad.

### Task 3
Test the app thoroughly and try to find as many bugs as you can. Address these bugs as you see fit. I will also be testing the app and looking out for bugs.

## Acceptance Criteria

- [ ] Task 1
- [ ] Task 2
- [ ] App tested and bugs fixed
