The program perceives the degree of proficiency of the students and consequently the difficulty of the presented problems is determined based on their success in solving the previous ones. However, if the student succeeds, the next problem will be a little bit more difficult, say 4y-8y. Another adaptive mechanism controls the proceeding from one level to the next one. A remedial student, who makes mistakes during the solving process, may need to solve more problems than the advanced student need. The final goal is that each student, remedial or advanced, will master the required degree of proficiency, before moving to more advanced topics.
Students can view their grades and the rules for passing to the next level.
