Hi,

I'm confused..

My code works for the given grades, but apparently the website want me to do it with their random ones..

So it doesn't work.. At start I made the simplyest solution, (like below) but that's not what they want either ofc, so I did add all they ask, still not the solution; I don't see what I have to do in fact.. Linked a printscreen of my current code.

```
grades = [100, 100, 90, 40, 80, 100, 85, 70, 90, 65, 90, 85, 50.5]
total = 0
for grade in grades:
total += grade
return total
```

```
grades = [100, 100, 90, 40, 80, 100, 85, 70, 90, 65, 90, 85, 50.5]
def grades_sum(scores):
total = 0
for notes in grades:
total += notes
return total
grades_sum(scores)
print total
```

Oops, try again. It looks like your grades_sum function doesn't properly compute the sum of all the grades! It returned 1045.5 instead of 37 for grades_sum([37])
