Pitt Mid Year Grades

Hello,
Today UPITT sent me a mail asking me to submit my mid year grades to them… I am wondering if this is a good sign or a bad one?

I posted before that Pitt asked for any senior SAT/ACT and also mid year grades for my son last year. His SAT did go up and his GPA went up slightly. He was accepted about a week after sending them in February. It seems that if kids on the borderline show interest and improvement, they have a good chance.
