As has been said, they are looking at the whole package. Don't worry about it.
As a raw PPL you are still learning (isn't everyone). The examiners know that full well. They will just operate a 'would I feel happy with this person flying over my house' criterion rather than be looking for test pilot precision!
I particular, if you feel that you have made a mess of anything - just ignore it. You are the worst person at judging how well you are doing in a test - leave it up to the examiner and more likely than not you will be pleasantly surprised with his judgement after a performance you thought was awful!
good luck!
