Unacademy is an app that teaches you tons of different topics from the comfort of your Android. Some of the finest educators in India (it's originally from there) are backing this project, offering you the possibility to increase your general knowledge directly from home.
The way Unacademy works is very similar to Khan Academy, one of the best educational apps you'll find on Android. Essentially you pick from different workshops and classes ranging on over 20 different topics. Each one is taught by a leading professor in their field who you can contact directly to ask questions.
One of the main points in Unacademy is that it allows you to specifically take on some of India's top exams: CSE/IAS, SSC CGL, IBPS/SBI, CAT, GRE, GATE/IES, CA, CLAT, JEE, Pre-Medical, Railways Examinations and many more.
Unacademy is one of India's top educational apps that'll help you on your way to successfully passing any of India's most important standardized tests.
