Presentation Class Level I and II are not formal RAD exam. The dancers will go altogether and with the teacher and perform some skills and dance to the examiners. The certificate will not have any marks and will only indicate whether the dancers can or cannot do.
My daughter has taken these two levels and learn the basic skills and know what the exam is.
If not take Level I and II, one can still take PP exam. But I think that Level I and II are interesting for beginners.
