UCAT HELP

Good day everyone, please I really need help or tips on how to go about that ucat. I’m really crashing out. Like I don’t know what to do . I’m using med entry and I keep practicing the questions but it’s not getting better. It’s like I keep failing and I feel stuck. I’m not dumb, I did well in my A level mocks. I don’t know what’s wrong. I feel like I have no guidance on what to do. Any help or advice will really do nice. I have my mocks in September.
