Most online courses/schools will either email or mail your diploma to you. If you are unsure, simply contact the institution you are attending, and discuss with them how they will be sending your diploma to you.
I am student in high school from Tanzania.
My questions are:
In which universities in U.S.A provides telecommunication/electronics and computer engineering?
How can I apply?
What Tanzania high school credits are needed in order to apply?
And, which subjects are needed in order to apply?
