If you get 50 marks out of 57 in a test what grade isit?

To find the grade, we need to calculate the percentage score:

(50/57) * 100% ≈ 87.7%

This is a very high score. A letter grade equivalent would depend on the specific grading scale used by the institution or teacher. However, on most scales, 87.7% would be considered either a B+ or an A-.
