I can honestly say this placement made a huge difference for my son. When they moved him into the harder classes he had explosive mental growth. It was shocking. He moved from a rather boring math class, to a class where they were learning EVERY way there is to answer a problem. New math, old math, logic, you name it, they learned it. They even had a math expert come in and work with the kids for a couple of days. He memorized some unpublished math shortcuts from the man which he still uses.
