You are required to disclose all schools attended and provide transcripts.
Were your first year grades okay? Did they put you on probation first?
Having a two year old during COVID would be extremely difficult. Do you have anyone else living with you who could help, or were you alone, taking care of the child and trying to do school work? Did you let professors and administrators know you were struggling, and seek accommodations?
It’s too bad the process of appeal is finished. I would have hoped for an administrator to understand and help.
But we know nothing about how you did before COVID, or what help you sought during COVID. I know many professors were giving extra time and incompletes but don’t know if you sought any of those.
You could perhaps take some classes as a non-matriculated student, and prove you can do well. As someone else said, you could also work as a dental assistant to prove your commitment to the field.
Until COVID is fully resolved, the school would have trouble believing you could do better because the circumstances have not changed. Or have they?
Maybe you need to take some time for things to settle with COVID, your child, and your plans.
