I am talking the rating on the problems not my personal rating for problems.
Tactics question reguarding rating

That's how it works in principle, but the rating change doesn't only depend on whether you solve the problem or not, but also on how much time you take:

Is the rating of a problem depend on who solved it for example if I solve a hard problem would the rating on the problem come down, and if I got an easier problem wrong does the rating go up?
