Is there a decent online GPA conversion scale?

<p>Or just a formula that one can use?</p>

<p>My school only grades on a 100 pt. scale, and weights to 105 for AP's. I'm assuming we're on a 4.0 scale and a 4.5 weighted scale, but they don't bother converting to that scale and I'm interested in seeing where I fall. </p>

<p>So I assume:
105 = 4.5
104 = 4.3
102 = 4.2
101 = 4.1</p>

<h2>100 = 4.0</h2>

<p>65 = 0.0</p>

<p>I'm not sure how things would fall in between there exactly. I can pretty much estimate it, but I'd really like to know my actual GPA. Can anyone help me out or at the very least, provide me with a link? Thanks.</p>

<p>There is no “standard” calculation of GPA; each school uses its own method.</p>

<p>Even among schools that use a 4.0 scale, there are variations. Some schools give extra eight to honors and AP classes, some weight only AP classes, and some don’t use weighting at all.</p>

<p>I got that. I pretty much have our weighting system all figured out. I’m concerned with UW, though. 65-100 range.</p>

<p>You can find one on the Princeton review site.</p>
