Many secondary school students in the Netherlands require additional support to prepare for their mathematics exams. This paper presents the design of a Massive Open Online Course (MOOC) featuring training materials tailored for the mathematics exams, integrated with a digital intelligent tutor. The tutor, which students can activate as needed, is embedded within the course content. Two versions of the tutor were developed: one powered by ChatGPT and the other by DeepSeek. To evaluate their effectiveness, both versions were tested on a set of problems from W4Kangoeroe, an annual mathematics competition for primary and secondary school students. The results indicate that while both chatbots are capable of generating correct mathematical solutions, their approaches often differ significantly from those provided by experienced mathematics teachers. This highlights the potential of AI-driven tutors to assist students but also underscores the need for further refinement to align more closely with educational standards and teaching methodologies.

Many high school students require costly private lessons to prepare for their final exams. These lessons go beyond what regular schools can provide. As a proof of concept, a distance learning program for exam preparation has been created using Moodle. It offers study materials that incorporate gaming and real-life applications. Each lesson begins with a diagnostic test and follows a specific training program to address students' weaknesses. An AI-based intelligent tutoring system has been developed to take on the role of a teacher and assist students with their work. After the system analyzes errors, the tutor provides specific hints and guidelines to help students solve problems accurately. The developed study material was tested on a group of students preparing for their final exams in mathematics.
