Teenagers at JFS took home the best set of results in four years, according to headteacher Jonathan Miller.
It was a record year at the school in The Mall, Kenton, because 77 students, almost a third of the year group, achieved at least A grades in all three of their A-levels.
Mr Miller said: “These record results, once again, reflect the outstanding academic achievement of all our students.
“We pass on our heartiest congratulations to all the students, their parents and our staff on such delightful examination results."
Individual achievements marked include Jonathan Davis, Rachel Grabiner and Chesney Ovsiowitz who scooped two A*s and two As apiece, and Jemma Green, David Miron, Gil Reich, Joel Rosenberg, Kirstie Trup and Alexandar Vukadinovic, who each earned three A*s.
Notably, 52 per cent of all A2 entries secured an A* or A grade while almost 83 per cent of results were at grades A*, A or B.
