Just received word that our youngest son has been invited to sit the Harrow Test in Autumn 2021. Our eldest son went through this 2 years ago, but he was invited to meet a house master in June, ie well before the Harrow Test which I understand occurs every autumn. Are there two streams, ie the favoured applicants get a preview in June? The Harrow website alludes to this but it isn’t clear. Insight appreciated!
