Online MA in the UK

I'm looking into doing a part time online MA in either AI or English and Languages and I was wondering if anyone had any experience/knowledge of how - if at all - this would affect the UC and PIP I'm currently getting. I've just had my UC appointment and she thought it was a great idea but couldn't offer any finance advice. I contacted the finance team and they said they couldn't offer any advice until I started the actual course 🤦‍♀️ if anyone could help I'd be really grateful as I don't want to start an expensive course they think I would benefit from then have no financial help at all
