I've done around 70 hrs worth of lessons 1.5 hrs a week I have no one around me who can take me out drubing between lessons! My concentration is bad after driving for 30 minutes I find Mt concentration dips and i keep making stupid mistakes like not dropping my gears at roundabouts and junctions and I don't even notice signs I feel like there's nothing else my instructor can teach me the mistakes I'm making are Purley my own doing! Hoe can I over come this and focus more, my test is in about 5 weeks and I just get told I'm a dangerous driver off instructor...my anxiety is starting to make me feel sick at the thought of another disappointing lesson...any advice?
