  Nowadays, E-learning system is considered as one of the main pillars in the
learning system. Mainly, E-Learning system is designed to serve different types
of students. Thus, providing different learning pathways are a must. In this
paper, we introduce the variability technique to represent the knowledge in
E-learning system. This representation provides different learning pathways
which supports the students' diversity. Moreover, we validate the selection of
learning pathway by introducing First Order Logic (FOL) rules. Keywords
