i think you should have got her here asap, because if she is 15 now, march next year she will be nearly 16? and kids in the uk the same age of her will be preparing for their final secondary school exams, so no point in her starting school march next year, i wonder even if a school would take her for a few months
also it will take her time to settle and adjust to the british school system
i suppose she could apply to go to college if she came in march next year, to start in sept.
i think she will have to pay international student fees for her going to college, could be £3,000 a year

and then for uni to..
as Non-EEA nationals are required to be here for 3 years before the start date of their course to apply for home fees
i'm pretty sure what i've said here is correct, but check with a college or with the immigration people
