Should you get a copy?
Some professors provide students with a copy of the letter they sent. Some don’t have the time. Ask
ahead of time if you’d like a copy - to see if your professor is willing to provide it to you. Whatever the
decision of the professor, respect it. If they’d prefer not to disclose the letter’s contents to you, then
don’t push it. If you’re sure they wrote you a positive letter anyway (because you checked ahead of
time, remember?), then rest assured they did. No one will write a letter opposite from what they
initially promised (unless you did something truly horrific in the meantime).
