That being said, schools won't process your application until your MCAT scores come in.
For some schools, they will send you the link to complete their secondary once your priamry is verified&transmitted (even before your MCAT score comes). So at least then you can start entering your secondaries during the month that you wait for the MCAT score, to have your application fully complete as soon as the schools get your score.
The timeline I'm envisioning in would be:
- Submit primary June 5th (with transcripts already sent)
-- Application is verified within the week
- Study for the MCAT & and finish pre-writing any secondaries
- Primary is transmitted to schools (without MCAT score) late June
- Start receiving emails to complete secondaries
- Take MCAT early July
- Take a break
- Submit secondaries to school
- MCAT score comes in early August (add additional schools to primary if necessary)
- Complete at all schools where secondaries were previously sent
Being totally complete early August seems pretty good.
