Not a question but a heads up Don't bother with codegym if you want to practice code on your phone while comuting, it is horrible to write code in their tasks on mobile. Like actually horrendus.... The reading part is fine but for a more all in all thing then get something else.

Why original developments are becoming a distinctive feature of the platform. Today, many digital platforms offer similar features, but some are creating their own exclusive projects, accessible only within the service. Do you think having such a section makes the platform more appealing to users in Nigeria?
