Statistically solo students are very very safe - instructors are paranoid about the standards they expect before sending a student up on their own, the tasks demanded of them are deliberately fairly undemanding, and the students are usually terrified of screwing up so are the most careful they'll be in their entire flying careers (except possibly when they become instructors and start sending students solo themselves!).
Just relax and learn to enjoy the flying! And do it all exactly as you've taught. And if you get lost, either turn a VOR/DME on, or call for a practice pan.
