Specialised Resources & Exam Prep
Through PrivateGeographyTutor.com, I turn my passion for Geography into targeted IB, A-level, and IGCSE exam prep. I create detailed, custom resources for every topic, using real-world case studies to make abstract concepts easy to grasp.
Many capable students miss out on top marks simply because they struggle to apply their knowledge under test conditions. I teach students how to decode exam command words, master complex data analysis, and structure high-scoring essays. Through personalised 1-to-1 mentorship and a focus on past paper questions, I build the confidence students need to transform their knowledge into higher grades.
Safety & Safeguarding
I hold a fully up-to-date 2026 International Child Protection Certificate (ICPC) issued by ACRO, a 2026 DBS Check Certificate, and I am fully Child Safeguarding certified.
