Is it ok if I skip some challenges or do them later? University final exams are comming up soon for me.

I would like to see:

1. Corporations treating their customers like people, not just bags of money.
2. Corporations and employers to stop spying on people. Like, it makes me feel so unsafe and that I can’t really trust them.
3. People becoming more tech literate.
4. Open source software, such as Linux being used by more people, especially those who are not so tech literate.

Ok, then C++.

For me it would be C/C++.
