Calculate a students current grade based on the following...?

Question

4 tests = 44% of your final grade.
1 Final exam = 23% of your final grade.
Homework/Quizzes = 11% of your final grade.
Lab = 22% of your final grade.

If the 4 test grades averaged 85%,
the Final exam has not yet been taken,
Homework/Quizzes averaged 95%,
and Lab averaged 98%...

Can the students current grade be figured without the Final exam not yet given? If so, what would it be?

Answer 1

Yup, it's possible. The entire class does this every sem before Chem finals. I'll teach you how, but since I don't have a calculator on hand right now, you'll have to do the actual computing. It's a simple stat problem (Math 101--seriously).

The equation is below. No variables. Input this on your calculator, and the answer will be the current grade. Of course, there are other ways of doing this, but this is the simplest for me.

(85x0.44)+(95x0.11)+(98x0.22)=___

Once you take the final exam and know the score, just multiply it by 0.23 and add it to the answer of the equation above to get the final grade. Clear enough?

Answer 2

You can take a weighted average of the existing work... however, you would divide by .77, rather than 1.00, because you aren't including the final exam in the weighting.

(85% x .44 + 95% x .11 + 98% x .22)/.77

The result is a weighted average of about 90%

Answer 3

this is tremendously not likely your professor got here up with this syllabus with out somebody greater up in the dept or the administration reviewing it in some unspecified time sooner or later. If he's been coaching for better than one 3 hundred and sixty 5 days, this is much greater not likely you are the only pupil who's tried this gambit. even with the undeniable fact that frankly, he won't be going to verify any of your argument when you admit which you probably did not evaluate his rules till now. Take the B+ and be certain you do not finally end up in a topic the place you should wrangle over tenths of a proportion element next semester.
