Low entry requirements- Northumbria uni- help

So I do EPQ, AS sociology, As psychology and Btech criminology. Psychology has been so difficult for me and I’ve done so badly in my mocks that going forward for best results my best option is to drop it for an AS next year. But I won’t have 3 alevels to apply to uni. I’d planned and the only course I really want to do is criminology with forensic science, has anyone had a similar experience with applying with a poor mix of qualifications.
It feels unfair to be dismissed straight away when my ucas points are the same, just they aren’t full 3 alevels. I’ve done work experience and will have a strong personal statement, but I’m sure I’m screwed to get into uni now. I want to go to Northumbria as it’s the only uni in the north east that offers the course.
Please help!!
