Sure Whirly et al will give their instructors advice too...
But Iwould say don't worry too much at 6 hrs - it ll come together.
Also weather/£/availablity permitting fly as often as possible to avoid having to re master the skills learn in the previous lesson.
Stick at it too! I know at 20 hrs I was still flying dual, (due to the FAA regs), I felt I couldnt do a thing right and was about to give up. That night I got rather drunk... next morning felt better and that afternoon solo'd after about another hour dual.
