My grade is a 65% and I got 100 on my summative that was weight 15% what’s mg grade

To calculate your grade, we need to consider the weighting of different assessments.

Let's break it down:
- Your grade on the summative is 100. This assessment is weighted at 15%.
- The remaining weight is 100% - 15% = 85%.

To find your overall grade, we need to calculate the weighted contribution of each assessment.

Weighted grade on the summative: 100 x 0.15 = 15

Grade before the summative: 65

New overall grade: (Grade before summative x remaining weight) + (Weighted grade on summative) = (65 x 0.85) + 15

New overall grade: 55.25 + 15 = 70.25%

Therefore, your new overall grade is approximately 70.25%.
