Question about mcc's admission process

hey there! im new to the site ( great site by the way). for those who go to mcc i just got a question in regards to the admission program. ok, so i know they do the last 12 credits thing till next year, and that they use your HS gpa if you dont have enough. i have more than enough 12 creds and yet i still sent in my highschool transcripts, i was just wondering if anyone else did that. because im getting paranoid that they might use my HS transcripts instead of my college gpa (which is better)? it would really give me good relief if someone replies
