Hello, everyone. Today let’s talk about study performance. Perhaps you are an average student with average intelligence that you will never become a top student. This is not necessarily the case, however. In my opinion, our concentration on studies is of most importance to us. Concentrating on our studies, everyone is likely to be a top student without additional work. Now it’s for each of you to discuss how we manage it.

From my personal experience, the planning of time is of the greatest importance. We must make a list of our weekly tasks. Then make a schedule or chart of the time. Fill in committed time such as eating, sleeping, meetings, classes, etc. Then decide on good, regular times for studying. Good planning will make you more aware of how you spend your time. Furthermore, it will enable you t9 plan your activities so that you have ad equate time for both work and play.
