We have the new papers, but as soon as we received them we were required to return the old ones to the CAA, so if your school gets the new ones you will not be able to take the old ones even before March.
Recommend you do the old ones ASAP if possible (if you still can), as it is likely that your instructors will have "tailorred" your teaching toward the the knowledge base required for the exams with which they are familiar.
