Oxford PPE Math

The schools I’m considering are Oxford and LSE (although maybe not now), UCL Econ, Warwick finance or econ, McGill commerce, U of M Ross (in state) and for a safety school Michigan state Eli broad business school. On a separate note, do I only write one personal statement? If so that would mean I can’t apply to both oxford law and UCL Econ for example because the personal statement won’t fit both.
