Hi there! I've applied for the Jardine foundation scholarship as well, I handed in all my documents two weeks ago. My personal statement was just slightly over 1 and a half sides (Arial, 12, normal margins) but that's already pretty long - I reckon it should be less, I didn't have time to really edit it down since I'm currently prepping for my IB exams. My counselor told me it should be about the length of a PS, or slightly less. I'm applying for Psychology at Magdalene Cambridge!
