A free app for Android, by GTSStar .co.

As a school-aged child, you’re already familiar with math, English, and all those basics.

But how well do you really know these subjects? This app is designed to test your knowledge of the basics of mathematics and English. It includes four different levels of difficulty: easy, medium, hard, and very hard. This is done by means of multiple-choice questions. The answers are provided at the end of each test, so that you can check how well you did on a particular question.

Some of the topics you will encounter – for both subjects – include:  Basic mathematics, common spelling, pluralization, and more. For the Flashcard game, the themes you will encounter consist of – but are not limited to: the English alphabet system, animals, city transport, fruits, vegetables, berries, professions hobbies, seasons, weather patterns, and elements of nature.
