Titles


I assume you are referring to FIDE titles. No, you would have to pay for the FIDE online arena for arena titles (e.g. Arena Grandmaster, Arena International Master) and in in-person FIDE-rated tournaments for regular titles (e.g. International Master, Grandmaster).
Chess.com does not use the FIDE rating system, called Elo. It uses a different system, called Glicko that rates players differently.
