Run at Thruxton, Mallory or Croft circuits throught the year they offer a safe environmen to practice road (and most track) skills. Braking down the day into 6 sessions you will get 1 instructor between 4 and they will help you, give you constructive feed back and answer any quetions you might have. You will get a short classroom input on an area of skill eg. throttle control, braking, vision ..etc then get time to discuss it with your instructor before trying it on track.
As the day progresses and speeds rise all of your new skills will make you more systematic, more accurate, smoother and as a result faster.
