If i have at the university the grade 9 at the seminar that is 33% and at the exam i have 8 and is 67% , what will be the final garde ?
That's a little garbled.....can you re-write the question a little more clearly??
If I understand your question that 9 grade constitutes 33% of your total credit, and 8 constitutes 67% of your total credit, then we have:
[.33 X 9] + [.67 X 8]=8 1/3 your final grade
