The 10 degree line and rule of 60 methods are commonly taught and seem to satisfy examiners. However the
only time I drew the 10 degree lines was for my flight tests.
I just do what Mike Cross does:
If you are on-track (which you WILL be at your departure point) and you can see a landmark ahead of you that is also on track, pick something that is directly between you and it. Could be a wood, a distinctive field, anything fixed, and keep it lined up with your landmark. If it starts to drift out of alignment adjust your heading to bring it back. When it's stable and not drifting right or left you are flying directly along your intended track. Check your heading and compare it with your PLOG to see whether the forecast and your calculations are accurate.
The examiner can't ask for a correction if you're never off track
