How I Use It
The only thing I use it for is to catch cheating students. If an answer sounds suspicious, I can usually find that it came from Brainly.
This is a horrible website that is used almost exclusively for cheating. Even though their so-called 'code of honor' prohibits students from answering or copying tests questions, test cheats make up a substantial chunk of Brainly. As in, it's what students pretty much ONLY use it for. They go there to cheat, and only to cheat, end of story.
