Qwntm, I hope you are more alert with your students than you are reading this bulletin board! If you had checked 'flyfishs' profile you would have seen he is in the UK, we do not have 'checkrides' here so everything you are trying to help him with is no help at all. Nimbus has it nearly right, but again falls down with using the word 'checkride' and 'skills test' in the same breath. We do not have check rides here, we have flight tests, or 'Skill Tests' under JAR.
Flyfish, your instructor is the one who knows what you are capable of, and you will have done dual flights to other airfields, so its no big shake for you to go on your own now. I always told my students that their solo qualifier, either PPL or CPL, was probably their most rewarding solo flight they could do (after 1st solo of course), so go and enjoy it!
