You asked a series of so basic, so naive, questions that showed absolutely knowledge of the process at your own school, much less AMCAS.
Quite honestly, it shocks me that any student past freshman year does not the basic process to order a transcript from his/her university, for any function, be it law, medicine, business, or a thousand other things. You go to the registrar
It also astounds me that any student considering applying to medical school would not have downloaded and read the AMCAS instructions, which are fully searchable. Below is from the official instructions outlining the complete process.
Transcripts
In the Transcript section of the application, you will determine whether AMCAS requires an official transcript from each institution you attended. If AMCAS requires a transcript from your school(s), you can create and print AMCAS Transcript Request Forms to send to the registrar(s)
Electronic Transcripts
AMCAS only accepts PDF eTranscriptsfrom approved senders who may submit electronic transcripts to AMCAS by means of a secure file transfer. AMCAS will not accept PDF eTranscripts by email or any other way. Remember that AMCAS accepts official paper transcripts from all institutions.
At this time, many schools that have the ability to send eTranscripts are not yet AMCAS-approved senders. If your college or university has not requested that you provide a Transcript ID, they are not yet an approved sender. Requesting an electronic transcript from a school that is not yet approved will delay verification of your application, as you will have to submit another request to your registrar for a paper transcript.
Transcript Request Forms
While AMCAS will accept transcripts that are not accompanied by an AMCAS Transcript Request Form, AMCAS is not responsible for transcripts that cannot be matched to your application due to the omission of this form. AMCAS strongly encourages you to utilize these forms. Any time you request an official, paper transcript for AMCAS, be sure to inform the registrar that the AMCAS Transcript Request Form should be attached to the transcript when it is sent.
Generate a PDF AMCAS Transcript Request Form by clicking on the Transcript Request Form button available on the Main Menu of the application.
The ID Number and Name on the AMCAS Transcript Request drop-down menus are populated by your entries in the Identifying Information section of the application. If this information is incorrect, you may return to the Identifying Information section at any time to correct or update the information you provided.
Verify and/or modify the School Address to which you will send your AMCAS Transcript Request Form. This address will automatically appear on the form when you print it.
