What would my grade in history be

I'm trying to figure out what my grade would be in my history class if I have:

Tests and Assessments Average: D (63.875/105.0)
Classwork and Homework Average: A (473/473)

The "Tests" category is weighted 47.1% of my grade.
The "Classwork" category is weighted 52.9% of my grade.

Thank you.

.471(63.875 / 105) + .529 = 0.815525
81.55%

(0.471 x (63.875/105)) + (0.529 x (473/473)) = 83.8%

NOTGOOD

probably a C+

Id say a middle B :)X
