There's no reason why you shouldn't be exactly on the outbound course before the procedure turn (and no reason for the instructor / examiner to expect you not to be within 5 degrees)
Why?
It's an ILS
(Which you will already have set up and idented - you just need to follow the back course to the procedural turn point).
So - actually flying the procedure, do it as follows.
ADF tuned to 341 (Misha) track inbound. Watch VOR/ILS (Nav 1, tuned to 109.3) and wait for the needles to become live. Start the turn BEFORE overhead the LOM, approx 2 dots on the CDI, so that you turn straight onto the outbound leg (fine tuning the turn as you go round). Determine Procedure turn point by flipping NAV2 over to 113.7 (GSH) and ensuring you're at 2400' level just past 347 Radial (NORNA). Execute procedure turn, flipping NAV2 back to 115.4 (GIJ) at the same time so that you're ready for the Missed Approach (if it happens).
