Pilot16,
If you are getting worried about going solo, I would add one small piece of advice. Do not be afraid to tell your instructor that you want a second opinion.
I am an ex military instructor with 3600hrs and there have been times where my bag of tricks ran out. I had to get another IP to fly with the student to try a change of tact/style.
Instructors are not infallible and a change might be what you need. Another thing is he might be padding his logbook with your money/hours.
Just something to think about. Best of luck, you will remember that flight for the rest of your life.
