I purchased the Personal Algebra Tutor (PAT). The system is not has functional as I wanted or expected, and there are several problems it will not solve, or certain problems will freeze up the system. The program is OK but there are too many limitations and several technical issues. It took three e-mail from their tech support just to activate the program. Montgomery Gross, VA
We bought it for our daughter and it seems to be helping her a whole bunch. It was a life saver. M.D., South Dakota
