FOUR QUESTIONS:
1) I mailed in my material on January 12 and still have not heard anything back - don't they usually send out acknowledgements when they receive the material?
2) If I mailed my stuff on January 12, and the university has rolling admissions, when should I expect a decision?
3) One of my schools said my transcripts and bank statement did not arrive. I e-mailed them confirming this and they never responded to my e-mail. So, I just re-mailed the material. Is this acceptable?
4) All of my mail was sent by "regular air mail," (I didn't send registered mail). OK?
