HEAD OF THE CLASS: The whiz kids of Mona Preparatory are the 2013 champions of TV J's Junior Schools' Challenge Quiz competition, after getting the upper hand against fierce opponents St. Richard's Primary in the recent championship final inside the TVJ Studios. The school, represented by Lee-San Gayle, John-Rhys Waite and identical twins Jevon and Jamar Ivey, has now won the competition thrice out of the last four years. But this year's victory was extra-special, if you ask principal Carol Blanchard. "It's a pre-anniversary gift," she says. "We celebrate our 50th anniversary next year."
