## Exercise 1
|
||
|
|
If you start with the `otherwise` statement, all grades will be F's.

|
|
## Exercise 2
|
||
|
|
It will still work, but the result won't be as expected. E.g. if you move `| y >= 0.9 = 'A'` below the B grade, then any grade of 80 or higher will be a B, because `0.9 >= 0.8` is true and thus it matches with the grade for B.
