After you submit your AMCAS, you can add new letters of recommendation to your application if you have not yet submitted 10 letters. Navigate to the “Letters of Evaluation” tab, then the “Medical School” section. Click edit and add the new letter you want to send.
As the applicant, you are unable to delete or change any letters that have already been submitted with your application. If your letter writer needs to update a letter they’ve written for you, they can upload a new version using the same Letter ID as the original submission.
Remember to “Resubmit Application” if you are adding a new medical school when you add your new letters.
