In Main School, children continue with their core and foundation subjects (English, Maths, Science, Religious Studies, History, Geography, Music, Games and PE, ICT, Art and Design) as in the Pre-Prep Department. In addition to these subjects, the children also start French lessons and have the option to begin to study Latin.

An average school day is as follows: Main School starts at 8.30 am, when the children are registered. Shortly after this, the whole school meets for a short chapel service. Three 40 minute lessons are followed by morning break, then two further lessons are followed by lunch. Supervised homework is timetabled after lunch, followed by a one-hour ten minutes games session and a final break before the two final lessons of the day. Main School finishes at 5.30 pm, with the option of staying for tea until 6.15 pm or 7.00 pm at no extra charge. The extended school day allows for a variety of academic lessons, extra curricular clubs, such as Chess, Art and French and a daily games session.

On Thursday and Friday nights, the children have the option of ‘flexi-boarding’ where they can board overnight. Pupils also attend school on Saturday, when they have the option to leave at 12.50 pm or 5.00 pm (if involved in matches). In practice, pupils attend two out of three Saturdays, with the third Saturday being an exeat (weekend off).
