Welcome from our Senior Prefect

  • Head Prefect

    Tosin A.

    Hello, I’m Tosin, Head Prefect at AGSB for the 25/26 academic year. It is a great honour to be a leader in the AGSB community and hopefully, I and the rest of the Senior Prefect team can help to enrich and expand the quality of provision you get as a student. I am so grateful to AGSB for shaping me into the young man I am today, and it is my sincere hope that every student finds themselves and shapes their unique identity whilst they are here. The AGSB experience can, in my view, be summed up in one word; courage. The school is a vastly rewarding environment to grow and develop in, if you have the courage to stretch yourself out of your comfort zone. It takes courage to stand up and perform on the stage in Musical Theatre, pick up a Rugby ball for the first time or speak in front of your peers in debating. This central idea of courage is what I think defines any student who walks these halls and wears a green blazer; it’s who we are. And we should be proud of that. As a Senior Prefect team, this year we are focused on Global Citizenship. Our hope is that once we all have a chance to engage in and learn about the issues that shape the 21st century, such as the environment & sustainability, human rights and social justice, AGSB students will be ready to go out into the world and drive the change that the world desperately needs. Turning on the news can be bleak at times, but AGSB fills me with hope that with bright, capable minds like ours, our fortune as a generation will most certainly change. I will be truly fulfilled to see every student try something new this year and push the boundaries of what they think is possible. For it is when we push past or limits that we learn more about ourselves, our capabilities and we truly live out those immortal words ‘Work Conquers All’.
