No one likes to fail.
However, its a fact that in the UK the pass rate is less than 50% so don't worry you are not alone. If you have learned to drive well and covered all the essentials passing your test should be easy. Unfortunately, the driving test is easy to fail too. A simple not fully stopping at a stop line or "thinking" your on a road with a different speed limit can fail your test.
