class struct or interface method must have a return type

So... you just post some code... now what? Nobody here can read your mind to know what problems you are having with this code.
Explain your self! At least say what you're trying to do and where you are stuck at.

By the way, you are missing an '{' after your namespace declaration.

my bad, it says for the SetGrade block of code it needs a return type but when i put grade or score it gives me the error

It looks like you aren't returning anything in the ToString method right now, if you don't return something it will error out. Also, the SetGrade method does not have a return type specified. Should be "public float SetGrade(float score)".

[AleMonteiro]

Oh, ok. Should be like this:

 public string SetGrade(float score)
 {
     if (score>=90.0f)
        grade="A";
     else if (score>=80.0f)
        grade="B";
     else if (score>=70.0f)
        grade="C";
     else if (score>=60.0f)
        grade="D";
     else
        grade='F';

     return grade;
 }

[overwraith]

Oh, yeah you're right should be string not float.
