Unnatural courses progress among users

Question

Recently I saw some users on the top of weekly/daily global ladder, which were making progress in pace of finishing several courses in matter of one hour. How is this possible?
I can imagine, if professional would start using Sololearn, he could finish one or two courses in an hour because it's like elementary for him, but I doubt even professionals could make 4 courses in different languages in an hour, even if they forward all lessons and only anwser question and quizes.
And for what I saw it wasn't only 4 courses in an hour, it was like 15 courses in a day

Answer 1

I don't have a PRO account to know for sure, but did you notice on any course the option UNLOCK ALL LESSONS?
Maybe this is the response to the question you are asking.
I plan to finish all courses, but in a natural way, in order to accumulate some information.

Answer 2

Romeo Cojocaru yeah that may be it but anyway, to finish course, and especially, to get certificate don't you have to make all quizes and tasks at the end - the 100% mark? It just looks suspicious, especially for a slow pacer, like me 😄 beside it's pointlessness, it just looks suspicious.
