Joseph,

great :-)

It is a friendly place to learn.

I have a suggestion about one way you might take your efforts to 
improve things.

<snip code>

Hard-coded magic numbers like 25 here are something it often pays to 
eliminate. If you know that every test or assignment for the entire 
future of time is out of 25, then it is fine. But, you can plan for 
the future and be more general by trying to accommodate varying point 
totals.

If you try that and get stuck, post about it.

Good luck with however you choose to improve your approach.

Best,
