Staff and pupils at the Kent school attended by shop assistant Clare Bernal, shot dead in Harvey Nichols, have held a service to remember her.
Clare Bernal studied beauty therapy at West Kent College
Miss Bernal, who grew up in Tunbridge Wells, went to St Gregory's Roman Catholic Comprehensive, where prayers were said in the chapel on Thursday.
"We send our sympathies to her family, especially brothers Phil and James," said headteacher Rosemary Olivier.
Miss Bernal studied beauty therapy at West Kent College after leaving school.
'Pleasure to teach'
Staff at the Tonbridge college, where she was a student from 1999 until 2001, said they were "deeply saddened" by her death.
"Clare was a quiet, hard-working student who was a pleasure to teach," said Angela Wheat, team leader for beauty and complementary therapy.
Miss Bernal, 22, achieved a BTEC national diploma at West Kent, which qualified her to work as a beauty consultant at the exclusive store.
"The beauty team were pleased to hear that Clare had continued to develop her skills and knowledge and had gone on to work at Harvey Nichols," said Ms Wheat.
Clare Bernal was described as quiet and hard-working
"All our thoughts are with her family and friends at this distressing time."
Miss Bernal had recently returned to live with her father in Orpington, Kent for her own safety.
Her killer, ex-boyfriend Michael Pech, had previously threatened to kill her, and was due in court next week for sentencing after admitting harassment.
He shot her in the head at the store on Tuesday, before killing himself.
Miss Bernal's mother, Tricia, from Tunbridge Wells, has paid tribute to her "beautiful" daughter.
