We provide self-study classes for Computer Science and Information Technology. These classes are accessible, open and dynamic: you can join, pause and continue any time. We improve the content very often, so by the time you have finished, some articles may be already changed.


Each class has one start page with references to related articles, video lectures and examples. Tutorial articles are opinionated and beginner friendly. If you read one single article every day you will finish any class in less than 24 days.

After you follow our tutorials you will have a solid base for deep learning and practice using real life projects. Do not expect to learn everything from your first reading. Read the tutorial a second time after you finish so you can remember better all you have learned.

We link with external references for further study. Our links are verified to be original and add-free. If you find a link that is presenting advertisement, please report it. We are not affiliate with any advertisement company or website.
