My DC in year 9 has a dtrong interest in doing a particular GCSE subject that's not offered by their current school, but it is offered nearby at School A (which is oversubscribed) and School B (which is undersubscribed). If we appeal for an in-year transfer to School A, can the panel hold it against us that School B has places and also offers the subject? I want to know whether they will be allowed to mention it, or ask me if we've applied there.
