## Description

<strong>Firefox add-on that embeds RateMyProfessors data directly into the UNCC course registration portal.</strong>

<strong>Credit &amp; Attribution:</strong> This is a Firefox port of the original NinerRatings Chrome extension. All credit for the original creation, logic, and design goes entirely to the original developer. You can find the original Chrome version <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/1e4d9afdbe7e45fc322529fca84503cd5388e4faa38551d6cdf245b03669f316/https%3A//github.com/ausmango/NinerRatings" rel="nofollow">right here</a>.

Tired of manually looking up every professor to see their ratings? NinerRatings was built to help Charlotte students streamline their registration process. Instead of frantically switching between tabs to pick the best option, this extension directly embeds RateMyProfessors data right into your Self Service portal! See professor ratings, difficulty, and would-take-again percentages without ever leaving the page.

<strong>Key Features</strong>

<strong>Disclaimer</strong>
Rate My Professors is an unofficial third-party website utilized by students. All reviews are to be viewed with skepticism.
- <strong>Availability:</strong> This extension only works on Charlotte's self-service registration portal (Browse Classes search), and no other university.
- <strong>Name Mismatches:</strong> Some professor names differ in Self Service compared to their RMP profiles. Some professors may show as 'N/A: no data found' even if they have data.
- <strong>Low Data:</strong> Professors with under 10 ratings may not be representative of actual quality.
- <strong>RMP Site:</strong> If RMP changes their endpoint, the extension may temporarily be down until fixed.
