Completed BA crime & Psych, did you do MSc or work opportunities??

I have a 2.1 in my crim & psych degree, and considering the MSc in Psychology (conversion) to gain BPA accreditation, but looking for others experiences with job opportunities after this specific degree without doing a masters!

Looking at NHS roles, I'm unsure if the MSc with the OU would help with getting into roles such as PWP, or trainee positions in mental health. What roles have you gone into related to psychology? Or have you gone down the research route? As I've seen a few MOD positions that I think would fit this degree but haven't been able to meet anyone who can give an insight into their roles.

I'm looking for interesting work, where I can either help people 1 to 1 or work as a team for projects, so these two options are my main goals. Currently working in youth work, which is the main part of my role but do activities for the wider community, so not sure if that bottlenecks me into youth services without the MSc to get accreditation.

Hope this makes sense. Thank you for any info in advance!
