Hello i am have to write a program that determines your grade for course programming logic and design i am using Visual Logic, and i need to find out how to total grades. I have put in 8 input statements saying Fname, Lname, ID, A, B, C, D and F. And now after these steps i cant figure how to do these next steps below:

2. Next total the grades

3. Next find the lowest grade

4. Next subtract the lowest grade from total

5. Next average the four highest grades

6. Next determine the letter Grade A,B,C, D or F

If anyone has ever used visual logic before please help me out if you can!!! there are input, output, assignment, if statements, while and for loops and exit loops. i need to know which ones too use to finish the project.
