Dont Worry
Pilot training takes every person a different time for each stage. Some people will find the circuit pattern hard and the next will find navigation tricky. Personally i found that radio navigation like tracking VOR's very hard to get my head round. Im sure that soon the day will come and from my view its best not to know when your going solo, when i did mine i wasn't expecting it at all and when we got to the end of my flight , the instructor got out and told me to go again!!! This was the best possible this cause then you are to busy to worry about being alone.
Keep up the good work and i look forward to a Thread saying "Just been solo"
