if  (95 >= Gall)    

Read this loud: "If 95 is greater than Gall".

No, you want the other way around:

if Gall >= 95    

The header of the function should show a warning in the editor:

function[A]=Q2pro(sum(homework),sum(midterms),FinalExam)
%                 ^^^^        ^ ^^^^        ^

You canot use functions in the list of input arguments. I assume you mean:

function Q2pro(homework, midterms, FinalExam)

There is no output "A" also.
