Are there things in challenges that are not in courses ?

Question

I'm always losing challenges because I don't understand them.

Answer 1

There shouldn't be. If you spot such, please report as out of scope.

Answer 2

i think everbody is losing at the beginning.. later on you will be ok..winning all the time..you are just new to this system and not get used to this environment..i am sure you will win all the time if you keep challenging..
there are not many questions here in sololearn.
I just memorize them first..later on i tried to figure out the solutions..actually they are correct.. I also thought that way before..👌👌👌👌👌
