No, you're not over-thinking it, but you do have a few small errors in 
your code:

Here you ask the user to enter a grade. Suppose they enter (say) 75. 
Your program will store 75 in grade, and then a moment later over-write 
that by storing [numberOfGrades] in grade.

I believe that what you need is to have a variable "grades" (note 
plural), and each time around the while loop, you need to append the 
current grade to the grades list.

Then, after you have collected all the grades, you can iterate over the 
list to get each grade one at a time:

for grade in grades:
     print grade


See how you go with that, and don't hesitate to ask if anything is unclear!
