Sixty teams took part in the Prep Schools competition, with each competing to try and win one of the 10 groups in the festival.
Bishop's Stortford, Danes Hill School, Dubai College, Seaford College and Warwick School all ended the day having won every single game.

In Group B Felsted beat Millfield and St Paul's, with each of the schools winning four and losing one of their games and Felsted taking it on PD, while Epsom College also won Group I by the same method ahead of Hill House.
Bedford Prep won Group H despite drawing against Clifton College as they went unbeaten in their other four games, while the Hawthorns School took Group C by five points on PD, edging out Cheltenham College Prep. Embley took Group E, losing to Terrington Hall School but topping the group after Terrington lost two other matches.
