We talked about the Kahn Academy app before. The website has been around for ages and is one of the most recommended free learning resources on the web. They have a variety of lesson subjects available but they are best known for their in-depth math and programming courses. Now you can work through practice questions right from the app, a real step in making this resource truly mobile.
Khan Academy has added over 40K practice questions to the mobile app so that you can bone up on your common core subjects, or, make sure your kid is getting that extra study time. They’ve also redesigned the navigation and search to make it much easier to use on your mobile device.
As always, you can access videos and articles and your account is synched across all devices and the web so that you can stay on top of your studies even when you’re switching machines. The changes they’ve made to the app will hopefully make it more useful to people looking to continue their education or just help their kids get a leg up. Kahn Academy is a free app and web service.
