Notwithstanding other posts, I'm still of the opinion that you're going too far too fast. I've discussed it with colleagues this morning and they are of the same mind.
Every sylabus I've seen for learning to fly puts navigation at the end of the course. First solo is followed by circuit consolodation, then off circuit work such as sector recce, steep turns, pfl's. It's done that way for a reason, you need to consolodate circuit flying and landings before you learn anything else. Go too far ahead and you'll loose what you've already learned. Further, when you've finally got around to flying the circuits you seem to need, you'll have forgotten how to steep turn, forced land and navigate and will have to repeat those exercises.
Doing things out of order is a great way to put hours in yours and your instructors log book. In the long term, it's also a great way to waste money.
Get some circuit practice in and if the weather's not fit, don't fly.
