My test
-----------
Test 1=62.4%
Test 2=70%
Test 3=70%
Test 4=75%

What do I need on the final to get a B in the class?
What do I have now?



A 93.5 – 100% C 72.5 – 75.4%
A- 89.5 – 93.4% C- 69.5– 72.4%
B+ 85.5 –89.4% D+ 65.5 – 69.4%
B 82.5 –85.4% D 62.5 – 65.4%
B- 79.5 – 82.4% D- 59.5 – 62.4%
C+ 75.5 – 79.4% F ≤ 59.4%

Tests:

Test 1: 62.4% of 125 = 78
Test 2: 70% of 125 = 87.5
Test 3: 70% of 125 = 87.5
Test 4: 75% of 125 = 93.75

Overall: 346.75/500

The final exam is out of 250, so overall so far you have:
346.75/750.

82.5% of 750 = 618.75

618.75 - 346.75 = 272/250.

This means you can't get a B because you can't get 22 points above the maximum. However, you can achieve a B- if you score 22.5 (so 22 points) in your final exam. :)

The tests will be worth 66.66666% of your final grade (2/3 of your grade) because they're worth 500 points of the 750 total points

The final exam will be worth 1/3 of your final grade

(62.4 * 125 + 70 * 125 + 70 * 125 + 75 * 125) / 100 =>
125 * (62.4 + 70 + 70 + 75) / 100 =>
(5/4) * (140 + 137.4) =>
(5/4) * (277.4) =>
346.75

So you have 346.75 points in total. You need at least 79.5% of the 750 points, 596.25 points, to make a B

596.25 - 346.75 =>
249.5

So, it is possible for you to make a B. You just have to pretty much make a perfect score on the final exam
