<p>I agree. My kid’s school uses 4 (regular) 4.5 (honors) and 5 (AP), i.e. they add .5 or 1.0 point for difficulty. They report weighted and unweighted grade points, and class rank using both weighted and unweighted grade points. I find this interesting. Kid’s weighted and unweighted rank are within 10 of each other. I take this to mean that, for someone with good but imperfect grades, the rank is affected by weight but not hugely.</p>
