It's been a long week, you deserve to take it easy for the next few days. Which is why we've rounded up the iPad apps that will do all the dirty work (e.g. "thinking") for you, leaving you free to kick back and let your mind wander.
Quick Graph: Even the most liberal of liberal arts programs often have a maths requirement, which means if you're not numerically inclined you're going to need a helping hand. Most lectures you can probably get away with using Quick Graph. It offers a huge array of computational and visualisation features, including VGA output for sharing your groundbreaking equation with the rest of the class. Free.
Human Body: While most educational apps are generally intended for children, let's be honest -- anyone not in the field probably remembers next to nothing about how the human body works other than the fact that, you know, it does. Fortunately, The Human Body by Tinybop is just as fascinating for adults as it is for children, letting you explore every excreting, beating and oozing crevice of human biology, all at your own pace. $2.99.
YouTube: Google's YouTube app just got a functional, stylish makeover this week. Along with an updated, Google Now-esque, card-based design, you'll also be able to enable your ADD by playing videos while looking for others, and devouring whole playlists. In the new version of YouTube, all you have to do is swipe down on a playing video, and it'll shrink down to a tiny version in the corner, leaving you free to do whatever other YouTube goodness you have to attend to. And if that includes searching for and/or watching playlists on your mobile app, you're in luck for the first time ever. The app's also getting a little tweak to help it play nice with the lovely Chromecast (or Google TV, PS3 or whathaveyou). Free.
