Transfer student receive decision after a week of application

Hi. I just received the acceptance from umich this morning. Btw, congrats to all admitted student for fall 2015

So I submit the common app on dec 30, 2014.
they received my official transcript on jan 2, 2015.
Today is the 9th, so it took them technically a week after all materials are submitted to give me acceptance. It is really surprising as i was expecting a longer wait to hear news back…

I am a transfer student from local cc in Michigan. Had a GPA of 3.8 and TOEFL 92.

just a reference, hoping all the applicants will hear good news soon!
