University of Florida GPA calculation?

I’m from an out of state private high school and I have Two quick questions:

  1. Our school doesn’t give transcripts to the students. Does anyone know how I can fill out the ssar? (Not a huge deal, I can talk to guidance counselour)
  2. What exactly is the coalition app? Is there a chance we won’t have to do the ssar because my high schools grading scale makes my grades look worse than they actually are.
