Assume that the test carries a weight of "x%" in your overall grade.
Suppose you earn a perfect score (100 percent) on the test.
Let's calculate your new overall grade:
New Overall Grade = (Previous Overall Grade * (100 - x) + Test Score * x) / 100
In your case, the Previous Overall Grade is 94 percent, and the Test Score is 100 percent. Let's assume the weight of the test (x) is 20 percent (for illustration purposes).
New Overall Grade = (94 * (100 - 20) + 100 * 20) / 100
New Overall Grade = (94 * 80 + 100 * 20) / 100
New Overall Grade = (7520 + 2000) / 100
New Overall Grade = 95.2 percent
Therefore, by scoring a perfect 100 percent on the test, your overall grade would increase from 94 percent to approximately 95.2 percent, assuming the test carries a weight of 20 percent in your overall grade calculations.
It's important to note that the actual impact of the test on your grade may vary based on the specific grading policies and weight distribution of your course. To obtain a precise answer, you should refer to your course syllabus or consult with your instructor for the exact grading criteria.
