I am doing my training soon and I like the idea of 2:1. I think it always helps with the learning to watch someone else do something and have their mistakes corrected because you can apply them to yourself.
However, I would be very happy though if I felt that I was deprived of the training I had paid for because the other driver was struggling. The way I see it is that I’m not just paying to pass an exam, I am paying for training and practice. Besides, even if I look like I’m doing alright, I could still have a bad day and fail which would be less likely if I had all the training I paid for. Therefore I think trainers need to be mindful of this.
The place I booked with does 2:1 and they have almost 100% 5 star reviews so I suspect everything will be ok.
