I think you'd need to ask your instructor as i imagine most people passed their tests with a regular handbrake.
Plus 2 for that, I'd never heard of an electronic handbrake, so I called my younger kid who's more car savvy than me.
He said that he almost bought one that had an E/HB when he was scouting around for the BMW that he drives now, and said that they seemed simple to understand and work.
I know how regular handbrakes work, but having owned only automatics since around 1988 I never use the handbrake, I just engage Park.
My wife goes bananas when she gets in her car if I've left it in Park and not applied the handbrake.
I just say, "Yes Red, I KNOW that you're technically right, and I'm in the wrong, but you're a civilian, I'm a professional, then I stand well back.
I have sometimes used the parking brake on autos in the U.S. if I've parked on a slope, and they can be unusual, applied with your left foot, like a kind of ratchet, then released by pulling a lever
