It is possible that the Instructor didnt really give a toss. Which is something you really dont want at an early stage.
I do however have to burst the bubble of the first solo. It is very very rare that a student will go solo at 10Hours. The norm is around 16-18hours.
There have been some exceptions to this. Guys will tell you they were solo after 4 hours. They probably had a lot of lessons before and could only log official hours after such a time. You could not cover all the pre-solo lessons in under 12 Hours safely.
Also bear in mind, that you may have to repeat one or two.
But when the day comes, both you and the Instructor will feel ready.
Stick at it, and try to book lessons as close together as possible.
With my students, I usually relate to the First Solo in the De-Brief, So each time they can see their progress and feel a little better about the progress they are making.
If you have access to the Flying Schools aircraft, Go sit in them and chairfly everything! Most PPLs will be so nervous because its a new environment. If you get comfortable with how the controls/buttons/switches feel you will be flying!
