You'll find that a lot of the 'official' R/T gets mutated (sorry... old habits!) depending on where you fly from, and who instructs you. For example, I don't usually ask for a radio check at all from Coventry....
When I do ask for radio check, for example if I've landed away somewhere, I ask for taxi instructions at the same time.
Stick with what your instructor tells you for now, and when you have your PPL make your own mind up.
