On Higher, grades 4-3 and 3-3 are a safety net for students who only just miss grade 4-4. A dash (–) means the board didn't set that grade in that series.
No exams were sat in June 2020 or June 2021, and 2022 was graded more generously on purpose, so our calculators use June exams from 2023 onwards.
