Transcript:
You should submit as soon as you have completed your application. You do not need to wait for letters of recommendation, official test scores or transcripts to arrive. Submitting as early as you are able will expedite the processing of your application. However, once submitted no additional changes can be made (although you may add additional school or program designations).
Personal Statement:
Begin drafting your statement of purpose and objectives (personal statement) for each program to which you plan on applying.
