THEN IT ALL WENT TO [zb] FOR ME
Hi garnerlives, When I was instructing on LGV, I found that quite a number of trainees ‘sagged’ in the middle days of their course. My own feeling on this is that you’re suffering from the common malady of being a human, so please trust your instructor to sort it out for you. 
I’d say it’s fairly normal and nothing to worry about, as you’ll probably start to improve during the next couple of days. My tip is that you just go with the flow, whilst listening closely to your instructor.
Good luck on test day.
