update the course material
Some of the commands listed in the lab is outdated and deprecated, I'd suggest review the content often and update it. Or at least put reference documentation in the course description so new learners can refer to up to date documentation. I'm available to discuss this further or help out.

Advanced course paths similar to other platforms
We need more hands on experience and intermediate ad advanced level courses like coursera offers for free because it's quite expensive..! This platform is very different when compared to those because we have the proof to showcase our talents immediately after we finish our final test..! And all the courses are free..😊
