Public examinations were disrupted in 2020 and 2021 due to the COVID-19 pandemic, whilst 2021/22 was a transitionary year in which pupils sat written exams with some adjustments.
Roedd nifer llai o ddisgyblion wedi gwneud asesiadau yn ystod 2020/21, yn sgil y tarfu parhaus ar addysg oherwydd y pandemig y flwyddyn honno.
