<p>I had a PE waiver for grades 7-12, but I was also playing a non-school sport for 20+ hours a week, traveling 1-2hrs each way for practice, missing a few weeks of school each year for competitions, and getting up at 3:30am for weekend practices. I can pretty well assure you that all of that negatively affected my GPA more than the waiver boosted it (but also that my athletic accomplishments meant more to my applications than +/- a few hundredths of a point in either direction would have). I used the waiver for an extra free period and the opportunity to end my day early (and go to practice) rather than to add another weighted course. With all due respect (and, I imagine, with some exceptions), there's more behind a lot of waivers than pricey rowing lessons and a crazed desire to improve class rank. Swap shoes, walk a mile, then judge...</p>
<p>I can't imagine that so many kids are getting waivers that your son's class rank will be seriously affected, but IMO, rank is the only thing worth being at all worried/irritated about, and only insofar as it's used for scholarships or automatic acceptance. GPA is close to a non-issue...colleges will recalculate it (not always factoring in PE) and/or will see through the mandatory unweighted courses. </p>
<p>My HS had two valedictorians, neither one of whom was #1 in the class. One of them seriously 'watered down' her GPA by taking 4-5 foreign languages, none of which offered honors/AP until at least the third year (and some of which didn't offer it at all). Princeton didn't seem to mind.</p>

Did really well, but one thing that brings his GPA down is that he takes unweighted classes required for graduation at school, such as PE, rather than getting a PE waiver to avoid the 4.0 ding on the GPA.

<p>Finally, if I may, a slightly altered perspective: unweighted classes are not bringing your son's GPA down. The privilege of being qualified and able to take weighed advanced courses is bringing it up. A 4.0 is not a ding; a 4.5-5.0 is a boost. If the school's ranking system doesn't reflect that, well, that's unfortunate, but it doesn't change the fact. He's obviously on an excellent track if a 4.0 looks like a "ding" :)</p>
<p>Best of luck to your son...I've no doubt he'll come through just fine, and happier for it!</p>
