Appraisal

Your driving might be fine.  Your instructor may have said so: an examiner, even, after a test.  But you might doubt them.  Maybe it's about you.

Take time away from lessons (and at no cost !) to chat with people you trust. People who know you.  They might see things about how you behave under pressure.  You can learn from that, then put it to good use.

If they've known you a very long time, perhaps as a small child, they may remind you how you conquered earlier hurdles, or handled setbacks.  If they've known you only recently, they may be more candid.  Both are good.
