What does the GPA scale is required field mean on the common app?

<p>I know my daughters guidance councilor should have helped us with this, but I have NO idea what to help her with…and one of her deadlines is tomorrow. Before the kids go back to school from winter break. Can anyone help us?</p>

<p>GPA scale refers to how the GPA is calculated. Some schools use 4.0 (so a B student would have a 3.0–this is the most common method), some use 100 and do it by percent so a B student would have around an 85, and some have other methods.</p>
