There were points that I drove so badly it was horrific. I can remember small things like sitting a red light and not having complete control over the car and my instructor having to grab the wheel but I cant remember anything else..why?
Now my Mum doesn't want to take me out for private practice
(I've have 35 lessons and I still have times like this)
If you have trouble remembering (and who doesn't under stress?) then you really need to make use of a written progress record. Re-reading this can help to consolidate skills and is invaluable in lesson recaps. Every professional instructor should provide something like this and keep it updated with written feedback.
