You can do it this way. Write down five other concepts that you think may relate to leadership, given the context of your exam question, e.g. middle school , community , student , resources , knowledge . Next write sentences that use leadership with each of the other concepts, for example 1. The vice-principal plays a greater leadership role in the junior high than in the high school. Community leadership often resists educationally necessary changes.
Students are less reluctant to exhibit leadership where adult support is strongly given.
Control of resouces can be the invisible base of leadership. Continue generating new sentences by pairing each of the six concepts you have with each other, e.g. Middle schools require more resources to help transition students into the high school model, etc. Using this method, and adding new concepts, you can generate many, many sentences in an almost mechanical manner. But generating sentences helps you unfreeze and is, at least, better than sitting and becoming more an more anxious by doing nothing. Students who have studied and with the help of their peers reviewed the vast array of materials from the doctoral program have little difficulty on the comprehensive examinations.
