There are no New Exams; there are supposed to be 9 subjects and 120 questions according to EASA but this is baffling the CAA who have nearly twice as many questions in the current 7 papers. All you need to worry about is passing the current exams within an 18 month period, then you will have 24 months from the completion of the last exam to obtain your EASA PPL. Sometime in that period the exams may well change, but you will be able to continue with what you have done.
