A few things
to know.

We offer English-language written Kotlin courses in PDF format. Each guide focuses on the topics listed on its own course page. No physical item is shipped.

Start with Free Kit and its introduction to program structure, values, and output. Then consider Spark Module for conditions and loops.

No. Each guide is a separate item. Read the prerequisites and choose the subject that matches your current knowledge. Higher-priced guides do not automatically include the other guides.

Written explanations, Kotlin examples, and practice prompts on the listed topics. Check the individual course page for its module outline. Live tutoring, video lessons, and an accredited qualification are not included.

The explanations and practice instructions are in English. The examples use Kotlin.

A device that can open PDF files is enough to read a guide. To run the examples you need a compatible Kotlin development environment. Coroutine examples also use the separate Kotlin coroutines library; setup requirements are explained in the relevant material.

You can read a PDF on a phone, tablet, or computer. A computer with a keyboard is more practical for writing and running code.

No. These are self-study guides, so there are no attendance requirements or fixed lesson times.
