angular frequency vs angular speed

In the circular motion topic, omega = angular speed. However in the simple harmonic motion topic, omega = angular frequency.
I assume they are the same but I'd just like to check before making my notes properly.
Thanks in advance.

They are related but not the same.

Circular motion is measured as an angular displacement with time and measured in radians per second. i.e. ω=2πf\omega = 2 \pi f radians per second.

SHM defines frequency in Hertz or complete cycles per second where 1 cycle = 2π2 \pi radians.

Ok thank you!
Would I be marked down for writing the wrong one in an exam?
