i was trying to get the overall numeric score for the entire course and final letter grade

but everytime i run the output letter will always D even if its a lower or higher number

Look at the your getLetterGrade method. Suppose finalscore is 86 - what happens?

Don't tell me what you mean to happen, walk through the code of the method and tell me what does happen.
