I wrote this code a few years ago to prove the insecurities of the Gradekeeper system in place at Gunn High School. Now that it’s been 3 or 4 years, they should have a different system in place, so I am releasing this… pretty trivial code, but quite functional.
While this was originally written to bruteforce grades from PAUSD, it should work fine for any place that uses Gradekeeper, with some tweaks for different directory structures.

System Requirements:
1: Anything besides Windows
2: Perl installed
3: GNU‘s wget installed
