I asked one of the professors to write me a recommendation letter which he thankfully agreed to. I then withdrew his name from the application and re-edited to another recommender, thinking that I had already missed out on the application deadline and assuming that the professor didn't send the recommendation per University deadline. I got an email from the professor inquiring for the reason I withdrew the request. I felt embarrassed about the whole situation and emailed an apology stating misunderstanding of situation. Has anyone been in the same position?. Appreciate any feedback.!
