<p>I changed highschools in Grade 10, for High School Ranks, will they use my GPA from Grade 10? to rank me? How does it work? Thanks.</p>
<p>It really differs from school to school, you would have to talk to your school's GC or officials about that. I know some schools include GPAs from previous schools even if they are totally out of proportion (my school does that). Some let you start brand new and only rank you according to what you have done in their school.</p>
