Model based on the learning needs of the student

This model is a more advanced version of the prior model. It has a tree structure with several branches which allows a student to go in depth into a particular topic. This model is based on the personal desire of students to learn since exams are not applied to place out of the topics (one could include an exam but simply to help the student decide if he needs to go into this topic). This is a model that assumes self-motivated students and is more applicable to professionals and people with higher education levels. It is up to the student to decide the topics and the depth in the knowledge tree.
