My daughter is studying A level, and parallelly studying for GCSE resits. She want to study science subjects in A level. She asked for resit for her GCSE science subjects in her current school. They didn't allow her to do resit GCSE in her school and they asked her to leave 'A' level if she is not planning to continue the current subjects. She applied privately for GCSE resit. We are not sure how to ask her school for taking leave during the exams. Please advise how to handle this, as currently we don't want her to discontinue current 'A' level before we get GCSE resit results.
