Rhiana, I would encourage your to call Tufts and ask the office to send you another packet as soon as you can (ie immediately). I had a similar experience where I destroyed one page on my U. of Pitt. secondary application. I called the Office of Admissions the next morning, politely explained my mishap (my printer has eaten the page) and asked for another packet to be sent to me. I don't know how friendly Tufts's Office of Admissions staffs are, but U. of Pitt.'s staff was very nice. About three days later, I got a brand, spankin' new packet in the mail. I felt like you...scared to call them. But I did it anyway and it turned out well. Good luck!
