If you're going to bed and having trouble the night before, as creepy as this sounds, if use as a meditation out there for you guys. That'll help you fall asleep and we'll talk a little bit about tests and ideas and it's really about US history but you could probably use that for other test anxiety nights that you're trying to fall asleep. Definitely look through the playlists. We're big on US history. We have a big US history and government playlist down there but we also have politics and world history and some other topical kind of videos that might hook you up. And then definitely look in the description because if it's not me that's going to help you, it's somebody else on YouTube. Whether it's going to be CPG Gray or it's going to be ViHard or it's going to be ASAP Science.
