What should i do ??????/

ok i just submitted my applications and my teachers sent in their recs as well. but only my transcript is on the school letter head while my teachers just uploaded a word file.

now,
is it necessary for the recs to be on a letterhead with a signature or is a plain word document without a signature fine (this is what they did)
should i ask them to print the recs on a school letter head, ask them to sign and then ask my counselor to send them through e-mail.com

You’re fine

Don’t worry, you will be fine. If there is any question, colleges will contact your GC.
