Most universities will require the applicant to provide letters of recommendation from high school faculty. Be sure to request and acquire these letters well before your application deadline. You want to give the person who is writing the letter enough time to ensure that ample thought and detail is involved. The person is more likely to provide you with a thoughtful letter when he or she is not being rushed.Try giving teachers and counselors a two week lead-time in order to prepare letters of recommendation, said Goldberg. We want you to be able to put your best foot forward and writing a strong letter takes time. Its like when you are writing a paper. You start out with a rough draft and take time to make revisions. Its the same way with a letter of recommendation.
Transcripts and other items should also be requested well in advance because it may take awhile to process. You want to make sure you have everything you need and on time.
