Circle has a lot of potential, with some great teachers. Unfortunately the school is incredibly disorganized, and students don't get what is needed. They pack four years into two, and for some actors that may not be ideal.
You can certainly learn in this school if you have not seriously studied theatre before, but you will be at a disadvantage, as the program is set up for fairly experienced actors, and does not have a lot of important things offered in regular college theatre programs.
I would warn off “newer” actors, and urge them to attend a longer program that will provide them with more opportunities, such as performances, auditioning, and networking. If you are older and have already had those opportunities however then this school could be a very good experience for you, as it is an intensive two year program that will give your the opportunity to really hone your skills- a cheaper versions of graduate school.
