Applied for Law at Warwick, haven't received decision yet. Possible to change course?

so i applied for straight law (M100) at Warwick but recently realised that i'm more interested in their law with humanities BA (MV21). i have not received any decision yet regarding my application for M100. does anyone know if it's possible for me to change course at this stage, and how should i go about it?
also if anyone has done or is doing MV21, how has it been for you? are we really allowed to choose absolutely any of the modules offered by the Humanities departments? thanks!

If you've decided that you'd like Warwick to consider you for MV21 rather than MV100, then simply contact their admissions team and ask.
See different ways to contact the undergraduate admissions team at https://warwick.ac.uk/about/contact.

thank you!!
