Grade for Class 3 Assignment

Good job, Ben.

#### Exercise 1

- No crashes, however it doesn't work as expected. 3 points.

It needs to say:

```ruby
"Take one down, pass it around, #{beer - 1} bottles of beer on the wall!"
```

So close. :sweat: 

#### Exercise 2

- No crashes, works as expected. 4 points.
- I thought you might like to see how a post-test `loop` solution might look.

#### Exercise 3

- No crashes, works as expected. 4 points.
- New lines between logical code sections helps readability :eyes:

#### Exercise 4

- No crashes, works as expected. 4 points.
- Nice use of `for` and the range :+1: 
- I thought you might like to see how small the loop body can get

#### Total

`3 + 4 + 4 + 4 = 15` :star:
