Feeling discouraged

I have 24 days left till exam and I’m scoring 50-60% on practice tests. I have the landini question book and I find some of the questions to be hard? I think pocket prep has easier questions but I’m not sure which is more reflective of the test. I’m also going to be honest and say I haven’t watched all of the videos from the course (Phillips) because I’m on a time crunch and the videos do take up alot of time. So far I realized I need help with understanding scope, all the calculations, mostly project integration management section. And which types are agile related questions?

Can someone suggest a plan or areas to focus on, what to skip, and how to best manage my 24 days. TIA

Edit- checked my answers and the questions I got wrong I got them first on the second try because I’m in between 2 choices and pick the wrong ones first try.

Update: Took practice test 1 = 69% Practice test 2 = 70%
