So I am using the Tactics Trainer unrated (without the timer) since the speed is not my goal at this point. When you finish a problem it tells you the Problem Rating = 1325, for example. Is this rating a Chess.com rating or are these 'official' problems rated according to FIDE, USCF, or what?

Thanks

Tactics Trainer rating.

It's just a general guideline to demonstrate the difficulty of problems to your skill on Tactics Trainer.
