Pareto Dilema

The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes .Hence you benefit more if you concentrate on the 20% rather than squandering your efforts on the not so productive 80%.
The students I teach, appear for a common examination with all others from the university. The examination is set centrally and generally certain topics get repeatedly more weightage as they form the backbone of the course. If one concentrates on this 20% , the probability of that person scoring good credits is higher than if she distributed her efforts over the total syllabus. As a teacher, am I doing right by insisting that a student should learn the entire syllabus? Last year two of my students cleared the entrance test to a top institution creditably only because I had covered every minor aspect also thoroughly. If I followed Pareto principle, many might do better in the final outcome and it will also give me more time to pursue my own interests. 20% of me says, follow Pareto but the rest of 80% rebels against it.
