<p>Is this possible? In case reading over my recommendation I notice a grammatically error etc?</p>
<p>I wouldn’t think so. I wouldn’t think recommenders would easily be allowed to switch in a new recommendation, especially after they’ve already submitted it. Also, it’d be a bit suspicious if you signed your FERPA waiver and they try submitting a new recommendation that’s largely the same, with a few grammatical tweaks to the letter.</p>
