Modelman,
I agree totally with Andy RR and Whirly.
Radio is one of the things most people take some time to learn and have no small difficulty with. It requires frequent practice when you are just learning it to get to know the lingo and get used to planning what you are going to say before you press the PTT button.
I should say, rather than working out routes, you would be better getting to know what each and every marking on the chart means and where to look for the things you are definitely going to need, such as aerodrome frequencies and LARS service frequencies.
Other than that, I suggest you concentrate on learning Aviation Law as you will need to have passed this in the ground exams before you can go solo.
Good luck, Modelman. Enjoy your flying.
Broomstick.
