Witam,
Piszę z zapytaniem jak w temacie- czy dane zdanie jest poprawne, a jeśli nie- jak je skonstruować by nie modyfikować go za bardzo?

Dziękuje za odpowiedzi

Is it?

Shouldn't there be a question mark?

A little, but I’d like to improve my english as much as I can :)

Shouldn't there be a question mark?
