Tassomai pulls their name from the Ancient Greek language, a phrase meaning “I organize myself,” as well as other meanings to do with self-assessment and improvement. Tassomai is a paid resource, with options for teachers and schools as well as for individuals. They offer three different levels of content, each with its own price: years 3-6 (£8.99/month), 7 and 8 (£29.99/month), and 9 to 11 (£44.99/month). While those prices may be steep, subscriptions come with a wide range of content from maths and sciences to literature and foreign languages. They also offer a guarantee of your student achieving a 7 grade or higher, or a full refund of your money.
