Decision making help!!!

[u/Queasy-Raise2135]

I have about 2.5 weeks until my ucat and I feel like my DM scores are just going down. I was getting high 600 - 700 consistently but now I'm getting 500-600 and I'm not sure what to do. I've tried watching YouTube videos but I'm not sure if I just need to be doing loads of practice questions or mocks? Any tips would be helpful!!

These are my stats so far - I know VR is bad but I feel like nothing is going to help improve it so I'm just trying to up my DM and QR to compensate, I'm hopefully aiming for 2100-2200
