Top 20 IGCSE Schools in London

London has one of the world’s deepest pools of British independent schools. Many run (I)GCSE/IGCSE-style programmes before A levels or IB. Families typically rank schools based on academic outcomes signals, subject breadth, teacher specialism, and consistent exam-technique training (mocks, past papers, feedback cycles).

What “IGCSE results data” looks like in the UK context

Schools may publish GCSE/IGCSE outcomes in different formats. Useful data points to request or review:

• Top grade proportions (A*/A or 9–7)
• Subject-by-subject trends (Maths/English/Sciences)
• Number of entries and cohort size
• University destination patterns post‑A level/IB (contextual)
