So, one of my subjects midterm I got 71% (43 out of 60). The mid-term test was worth 25%. It is my first evaluation.

How do I calculate my final mark so far? :|

If your only grade this term is the midterm, then you have a 71% average.

Are you asking for your letter grade?

56%

To calculate your final mark so far, you need to consider two factors: the weightage of the midterm test and the grade you earned on it.

First, determine the weightage of the midterm test. You mentioned that it is worth 25% of your final mark.

Next, calculate the contribution of your midterm test grade to your overall mark. Multiply your grade by the weightage in decimal form. In this case, 71% is equivalent to 0.71 as a decimal. Multiply 0.71 by 0.25 to find the contribution of your midterm test to your overall mark: 0.71 * 0.25 = 0.1775.

Now, add this contribution to your current overall mark. Since it is your first evaluation, you don't have any other grades, so your current overall mark is 0.

Finally, add the contribution calculated in the previous step to your current overall mark: 0 + 0.1775 = 0.1775.

Therefore, your current overall mark, after considering the midterm test, is 0.1775 or 17.75%.
