Good luck with your lesson today. Jee this brings back memories.
What you will find as you go through the course is that things are done in a logical order. No point in being an ace at landing if you can't fly straight and level. One lesson leads onto the next very well, and as I said Neil is a very patient and good instructor.
You will find that instructors will let you make certain mistakes in the hope that you recognise them and correct it. What ultimately an examiner is looking for is not that you are an undoubted ace of the skies, but that you can fly reasonably well, and more important than that make good safe decisions in flight, and that is probably the major point.
