I've been teaching IGCSE & AS/A levels students since the past 4 years . My aim is to create conceptual understanding amongst my students . By referring to various study material, I make my students well versed with different kind of questions asked in the exam . Grade 9 is crucial as it builds the foundation for the official O levels and going forward with A levels . 
I'm in the process of introducing my own book of compiled questions topic wise too to help my students perform better . 

The topics in the syllabus seem simple and many teachers claim to teach this to IGCSE & AS/A levels students but the way the questions are asked in the examination for IGCSE & AS/A levels students is very different and not many teachers are able to help with that . Whereas I've studied the way in which the papers are set and my USP is mainly to endure that students can answer the examination well . Many of my students have been toppers of their schools in the past .
