Assuming you mean revalidation rather than renewal, within the 12 months preceding the expiry date of your rating, to revalidate by experience, you will need to have completed 12 hours of flight time in the SEP class, including:
— 6 hours as PIC,
— 12 take-offs and 12 landings, and
— refresher training of at least 1 hour of total flight time with a flight instructor (FI) or a class rating instructor (CRI). (This can be achieved in as many flights and with as many instructors as you wish.)
There is no such thing as 'P2' on SEP Class aeroplanes.
