My school does not start writing the committee letter until after you submit your application. They say it takes about a month to write it. According to one advisor, the committee letter does not hold back the application and it still gets sent to schools without the committee letter. I'm questioning that because he did not seem to know that much about the AADSAS application. Does anyone know for sure if it still gets sent to schools or will it not be sent to schools until after they upload the letter?
