waiving your rights does not mean you have not seen the letter. my professor gave me the letter to edit before he submitted it, but i still waived my rights on the application. i may be wrong, but i think you waive your rights to access the letters after they have been submitted to the school. letters are supposed to be sent directly from the writer, so it is understood that applicants have only seen the letter unless the writer has given it to the applicant. imo, waiving your right to access letters is the courteous thing to do. afterall, if the writer wanted you to see the letter, he/she would have given it to you. the only reason not to waive your right is if you want to access your letter without the writer knowing it. personally, i think that is wrong.
