The state of mind with which a student approaches study will determine the results that student gets from the study.
The student must determine what he is going to do with the materials he is studying. He must determine what he is going to do with the information he is absorbing.
If a student's intent is to study the materials so he can pass the exam he will be very incapable of doing anything with the subject once the exam is over. He might be a great theoretician, but he will not be able to use the subject.
Some students don't have any intention other than getting through the course. They are just there studying away. They balk at doing demos or clay or looking up words for their exact meaning. Even when forced to demonstrate something they maintain the attitude that it has nothing to do with them. „It's all very interesting to read but… “
Non-involvement is the primary barrier in the ability to apply the materials of a course.
There can be many reasons for study. Points, exams, status, speed, glory, whatever.
There is only one valid reason. Studying for understanding, application and practice.
