Hi Aerofoil,
I am an instructor and I'm certainly not going to second guess the guy (guyess?) you have been flying with. Be wary of setting too much store by the answers which you will get here from unknown sources. Do speak to your instructor and, if not satisfied speak to the CFI. Ask them for a review of your overall progress, they have the experience and the specific knowledge of your performance to give you the answers you need.
Good luck with your flying and especially that first solo!
PS, let us know on here when you have done it!
