SOPP591: My dream is to get into the Royal Academy of music

This question was sent by Justina. And she writes, Hello, my name is Justina Pupeikytė and my dream is to get into the Royal Academy of music and after that become a professional organist. But there are few things that are keeping me down. I have very poor sight reading skills and weak transposition. I also learn musical pieces slowly. I am not talking about slow tempo while playing that concerns me, but the time that it takes for me to learn the piece and it's long. Can you help me? Thank you.
