How serious do you guys think Duke is about their 16 day deadline in filling out their secondary? I didn't think they were serious at all until I saw (over a month later, I know I'm a slacker/procrastinator) that they want you to put the date + 16 days past that you received their invitation to fill out the secondary. I was planning on filling it out, but I'm wondering if it will be a waste of $75. I emailed them and they told me as long as it is in by December 15th, but what if they only want my money? Why else would they want to know your deadline on the application?
