Even better, if you have MSFS or X-Plane, sign up with VATSIM and fly online with real ppl providing ATC service. Pick up an IFR clearance then fly your route, all for free.
I'm just about done with my instrument training and VATSIM has been incredibly helpful in the process. On my very first IFR flight, I picked up the clearance over the phone from the TRACON, departed (non-towered airport), flew the enroute portion, then did several practice approaches at a Class C field, handling every single radio call, including the dreaded approach clearance that usually leaves student pilots with their jaws agape.
The instructor said he'd never had a student work the radios on their first IFR flight. That would be a direct result of many hours of flying on VATSIM.
It's one thing to LISTEN to a clearance, but as you know, it's another to also have the confidence in reading it back.
