Computer Programming: is the second course for Computer Science. After this course you will be able to understand and use one or more programming languages. This course is required for Software Developer, Website Developer certificate and Database Developer certificate.


In the next YouTube playlist you can watch a short introduction to 12 computer languages. I describe the main features of the language. This will help you to decide what language you chose to learn. If you’re familiar with computer languages you can skip to deep learning.

Introduction to Programming Languages


For beginners we recommend: Python or Julia. For these languages we have created extensive tutorials to explain  programming paradigms and language syntax.  These two exams  have low difficulty and are designed for learning.

For senior programmers we recommend a secondary language: You can start with Go or Rust. Next C# and C++ are good if you search for a job. Swift and Java are more difficult to master.

For web programming you can learn HTML+CSS and JavaScript. For databases design you must learn also SQL and PL/SQL languages. To become a full stack developer you need: HTML+CSS, SQL, JavaScript and Java or Python. A system programmer can chose Rust, C++ or Assembly.

Deep learning

Next is a list of most useful languages. For each language we have one introductory video and links to documentation. For some languages we offer premium tutorial that teach you sage codding. If you are a registered member you can also take an exam.
