Problems with the PMP mindset (I don't feel well)

I am thirteen days away from taking my second exam for the PMP certification, I already failed the first exam in November. I have been devoting a lot of time to studying, I have a wife and children and a 10-hour-a-day job. The problem I see in my process is that instead of moving forward with the percentages of the SH simulator, it seems that I am going backwards. For my first exam, I had 75% in test questions and 72% in test mini questions and in the full exams and mini tests, now I have 71% in test questions, I have already done each question at least three times. I don't think it is due to lack of dedication because despite being tired every night, I study one to two hours a day or until I fall asleep from exhaustion and at least 4 hours on Saturdays and Sundays.

I was also recommended to take the tasks in which I got a poor result in my first exam according to the report that the PMI sent me because these correspond to the ECO task list, the problem is that I cannot find a single document where the topics for each task are detailed according to the order of the ECO, so I would have to search through many documents and that is not useful.

In the first exam I failed, but I failed miserably in the areas of PROCESSES AND PEOPLE and someone told me that the most likely thing that had happened to me was that I could not apply the mentality. Many members of this forum say that you have to get the mindset to answer questions, I, for my part, have read the notes from Third3rock, AD, DM and MR, but I don't see how to apply this to 90% of the questions. I don't know what's going on, I'm quite worried because I don't see the light at the end of the tunnel with this mindset thing.

I would really appreciate it if you could help me with your ideas on how to apply the mindset to the questions, if possible with examples or if you have some notes that you have taken and you think they can help me, I would appreciate it if you could share them with me.

I know, my English is terrible.

I appreciate your attention and send you my regards.
