Two App Questions

  1. How do I know what is required and what is optional? I have trouble remembering what year my dad got his Bachelor's and was thinking whether it is okay to leave it blank, as the validation was successful.
  2. Here is an excerpt from the MIT site:

An official transcript submitted during the application process will be recorded as “College Transcript” in our database. If you submit an unofficial college transcript, the information will be entered as a supplemental document in your file. Enrolling freshmen who would like their college courses considered for credit transfer will be required to submit an official college transcript.

So if I submit an official college transcript, would it even be considered in the application process? I know that it won’t transfer, but am I better sending an unofficial one?
