What appears to me the worst aspect of this is the apparent complete lack of communication between the two instructors, or incomplete student records, so that neither knew what you had or hadn't done. Even if the records are incomplete, it doesn't take a moment to ASK you if you've done the exams, how much solo flying you've done, etc. It sounds like total incompetence on that kind of level. Unfortunately it's not unusual. The PPL course tends to be a DIY course to a certain extent for many of us, and it shouldn't be!!! I'd suggest changing schools, but you sound as though you're so near finishing anyway that it's not worth it. So do some research yourself, find out what you don't know, and make sure you learn it. You sound like you're doing fine IN SPITE of poor instruction.
