Problem with counters

[Beginner0001]

I need to make mod-12 asynchronous down counter using T flip flop. It counts from 15 to 4. I don't know really how to do it and it's really important, so if you could help me i would be very grateful!
Thanks

The only person that would "need" to do that would be a student. There is a sub forum for homework.

Okay thanks. I've found it.
