If you’ve taken any high school-level math or language other than English courses in 7th or 8th grade, you can enter them on this page.
• 7th & 8th grade courses do not need to appear on your high school transcript.
• Only enter courses with grades of C or better.
• Math (including the Geometry requirement) and Language other than English (LOTE) are the only subject areas that can be met by course work in middle school.
