Claire Manton proved her fitness as she swept to five titles at the Sussex Championships at Crawley.
Claire, 15, from Hove, won the open and junior 200m individual medley and 100m breaststroke and girls' 100m 15-year-old backstroke.
The Blatchington Mill pupil has suffered from flu.
She is ready to represent England, with Ben and Chris Hutchinson (Crawley), Holly White (Brighton), Amy Kent (Brighton) and Jodie Miller (Haywards Heath), at the Home School International in the Republic of Ireland this month.
Claire said: "My form showed to me that I am fully over my illness. I felt good."
