USAGE
Intense and intensive are clearly similar in meaning, but they differ in emphasis. Intense tends to relate to subjective responses - emotions and how we feel - while intensive tends to relate to objective descriptions. Thus, an intensive course simply describes the type of course: one that is designed to cover a lot of ground in a short time, e.g. by being full-time rather than part-time. On the other hand, in the course was intense, intense describes how someone felt about the course.
