What should I be doing for the MAT in the past few weeks?

So the MAT is officially around 3 weeks away and I'm just wondering how exactly I should be revising? I feel like my scores on past papers vary quite a lot and I'm wondering if there is a good strategy for getting consistently really good results. Also with the TMUA also soon, should I focus more revision on TMUA or MAT as MAT is most likely more important for me and I find the TMUA easier anyways.
