Are you talking about your Bronze C? If so best of luck and I admire your confidence that you can predict you will be doing it next week! Two half hour flights off a winch launch or two one hour flights from an aero tow - took me weeks after my first solo or was that months!
If you are going for you Bronze, best tips are 1- relax on each flight, 2 - remember to make sure the barograph is switched on.
