Dismissal from nursing school without failing any course

I am supposed to enter my senior year in a BSN program by August, i already completed 3 semesters in the program. I just found out my nursing program sent my a dismissal letter for what they tagged “unprofessional” behavior. These behavior includes calling my teacher less than one hour to a lab class to get permission to be absent due to sick health, waking up late due to a sickness and could not attend a 6:30am clinical which i already made up, not being able to review my nursing exam afterwards because i wad having serious anxiety attack, etc. The point is that look for every opportunity yo write me up because I’m one if their best and the only black.
