For finals, how can I find out how low of a grade I can get on the final to get a certain grade?

Question

ex- I have a 77.23% in the class right now, the final is worth 20% of my grade and I want to get a 80% for my final grade. How would I figure this out?

Answer 1

Is the class math? 8-)

77.23 x 80% + G x 20% = 80.00

.2G = 18.216

G = 91.08

Good Luck!

Answer 2

It used to be easy to do this but now different schools/teachers have new scales so not that easy anymore! Basically go into it like you are going to do great and get 98% of it right. You will tell yourself this repeatedly & then do better on the test. You may surprise yourself! Good luck.
P.S. Ask the teacher. It depends on how many ?'s are on the test too & what the points are worth. If you have one that has essay answers worth 3-5 points each it's too difficult to give you a definitive answer on here. Hope this helps.
