The field of Intelligent agent is one of the important fields of Artificial Intelligence. In this research, we are proposing a Multi-agent system for an educational application. The system includes Explainer module, problem solving module and evaluation module. The system has a graphical user interface and can be connected to the Internet. In this paper, we describe all of these modules of the tutoring system except the explainer module which was been presented in a previous paper. The student can go through all the lessons of the domain knowledge through the explainer, then he can go through the problem solving module which shows a set of problems and gives the possibility that the student can solve this problem step by step, the answer go through the evaluation model which analyzes them and identifies the problem areas which has difficulties of the student and shows how we can treat these problems, also it stores the scores of the student in student record and shows it to him if he ask for that in a self explanatory form
