With respect to kernel and core front end features, there is NO difference between the professional and student versions of Mathematica 3.0. It may be that the systems of equations that you are trying to solve do not admit a closed form solution, or you may be using inappropriate syntax to solve the problem. You may want to post a simple example of the problem you are encountering to MathGroup or to the student support forum at http://www.wolfram.com/student-support/ -- P.J.
