Is it OK if you publish Practice tests with questions that available on internet, too?

[tiborszaraz]

If you would like to do a practice test then is it ok that you use questions and answers from the internet (and those questions are available on many places more than 1 on the internet - as practice questions)

The advantage is that although you use public questions, the students can practice with real-time duration the exam.

OR

It is not allowed to use questions that available on the internet and you have to overwrite it at least?

TL;DR: No

Do you own the copyright to those questions?

I assume not, since you say they are public.

Since you do not own the copyright, it is illegal to publish them, and even more to profit from them.

Same thing if you find youtube videos, download them and make a course out of them. It is illegal, stealing, and immoral.
