Scores and Grades in internal examinations

I have persistently maintained A1s in all subjects in school right from Nursery to 10th. In 10th grade I received 10 cgpa in the board exams. I have almost always got full scores in all my school exams may it be formative or summative exams.
Overall till date I have maintained above 95%.
I am in 12th now and awaiting my final board exams.
