My professor accidentally sent the draft version of the recommendation letter to UTD and it had a mistake of the university name as "[Enter university name]" which was supposed to be replaced with the intended university name. It was submitted into a portal. Is there any way to remedy this? I've already submitted the application and emailed them about the mishap. What are my chances to remedy this situation?
Admission committees get this sort of thing frequently. We understand your professor's situation (because we write lots of recommendation letters ourselves). It is very unlikely that a committee would even bother to comment...
... and a tiny mistake on your professor's part certainly shouldn't affect your chances of admittance.
