What Sets Us Apart

Through years of invaluable teaching experience, Dion has encountered a wide array of question types from top schools, including the University of Cambridge. He has witnessed the evolution of the syllabus and nature of the examinations throughout the years. With this, Dion has devised novel ways to relook at the chapters to convey them in a simpler way.

Instead of memorising textbooks and notes:

  • He advocates the observation of concepts from a different perspective to develop a clearer understanding.
  • He also encourages students to cross-reference and apply concepts learnt across various topics or disciplines instead of learning each chapter independently.
  • Learning is made visual by using concept maps and mind maps.

Personalised Attention

Our small-group setting provides a more conducive and comfortable learning environment with increased opportunities for a one-on-one interaction.Interactive learning is promoted as students engage with their peers, but individualised attention is given to each of our students.

We also pride ourselves in providing prompt responses to all questions and comments.

Our Teaching Methodology

With Dion’s two decades of teaching experience, he has developed his own lesson model that has been proven to be effective over the years.

  • Detailed concepts through demonstration and daily examples
  • Linking concepts across topics
  • Relating concepts to research trends and industrial practices
  • Learning through Doing (LTD)
  • Selected past year preliminary examinations’ questions and solutions for practice
  • Detailed analysis of examination answer scripts and prescription of remedies to overcome losing marks
  • Analyses reports shared with parents for areas of improvement
