It looks like a great book!

What confuses me is, I see it has an "average" customer review of 5 stars.
Doesn't that mean ALL 25 reviews are 5 stars?

But somehow it does NOT mean that.

Are there no 1/2 stars, and/or does Amazon round upwards?

If I have a 4.0 GPA, doesn't that mean I have never received anything less than a 4.0?

Just wondering.
