Well, this is us too. MUS for 2 years, then tried MM, moving to CLE this year. So far so good. DD LOVES The timed drills (???) and she's always been one to freak out when timed. I don't know, but she's digging it. We actually went back to the beginning of 2nd and are moving forward from there. Lots of review, a few little gaps here and there, good for building her confidence.
