Mock Driving Test

I went on my driving lesson yesterday and we did a mock driving test.  I failed.  After we’d got back to the test centre, Dave my instructor, said ‘Well I think you know you failed.  You did things that I’ve never seen you do before!'   And I had, I’d driven off from a junction in second gear TWICE!.  I still would have passed regardless of all this but then I took what seemed like half an hour to move onto a dual carriageway and this was a serious fault as a van moved alongside us, got tired of waiting and went before us.  I have another lesson tomorrow.  My test is 11 Feb at 9:17!  And if... I mean when I pass, I need a note from the examiner and Dave saying I can drive our car.
