Pull to refresh is refreshing too quick on the Grades page for IOS.

[Trit0]

Describe the bug
On the grades page, when you have a lot of semester on your account. If you go to the bottom of the page and then scroll up, the pull to refresh starts loading in the middle of the page. Normally, a pull to refresh starts loading when you try scrolling up when you're already at the top of the page. My guess is it starts loading whenever you scroll more than the viewport height.

To Reproduce

1. Make sure you have a bunch of semesters.
2. Scroll to the bottom of the grades page.
3. Scroll up
4. It should start loading before reaching the top of the page

Expected behavior
Normally, a pull to refresh starts to load when you try scrolling up and you're already at the top of the page.

Additional context
My guess is it starts loading whenever you scroll more than the viewport height.
