Will be better to have it and not use it right off, and having shunting experience means at least the scary reversing when you start out won’t bother you so much
Back in the 80s when you could go direct from car to the old HGV class 1 (now CE) I did one year on nights shunting artics in a yard before going for training & test
It helped so much that my fellow trainee had 95% of the reversing time
