Never attempt to correct a trimming mistake with more trimming. I doubt anyone will notice other than you, just let it grow. BTY, your beard and haircut look pretty awesome too! Haircuts with short/faded sides go well with a full beard. Looks like I have completely missed your beard thread, sorry about that. Thanks for your service to our country.

Good luck with getting your degree and I hope it is in a field that will allow you to keep the facial hair.
