Corrections don’t mean your thesis is incorrect.
They are the typos and mistakes that crept past the editing process. A correction could be a suggestion that you direct the future reader to another reference, or direction to improve clarity for that future reader. They’re the ideas from experienced academics steering your work to a good place.
Corrections aren’t the system’s response to imperfection. They’re not given as a punishment. They’re not asked for on a whim.
A list of corrections is the answer to the question, “What changes would help your thesis be the best it could be?”
