So you failed classes a College A (the school you want to graduate from) and retook them during the summer at College B?
Grades from College B most likely don’t count in your College A GPA hence the probation - the F’s are still pulling your GPA down big time.
And schools do have limits on how many hours can be transferred in and qualify for progress towards a degree, which classes can be transferred in (often not upper level courses in your major), things like that. So mixing and matching classes and college is fraught with peril, especially when you’re close to graduating. IF you do eventually go back to this or another school, make sure you get a full accounting of WHICH classes can be used towards a degree - and get.it.in.writing.
