<p>Say that a school has a normal grading scale so the scale is a 4.0. Since there are courses that are weighted at the school, would the scale be 4.0 or 5.0?</p>
<p>There sometimes seems to be more weighting methods used than there are high schools. What the scale is really depends on weighting method used. If a school has a 4 point scale, it may add a point for honors and AP, for just AP, for a limited number of honors and AP. other possibilities, thus giving those courses allowed a potential of 5 maximum. However, others may only add 1/2 point, some may add no more than .1, many methods exist. Moreover, they may weight for an A, B, or C grade, or only for A or B.</p>
<p>At many, what you suspect is true, an A in a weighted class becomes a 5 if 4 is highest for non-weighted grades, but it really depends on school. The variety of weighting methods is why many colleges simply ignore the particular method used by a high school and determine grades to be relied on by using their own weighting system (and the methods for doing so vary among colleges).</p>
