Exam prep on your own.

I was regularly notching 50-65% on practice exams across the internet. I passed the PMP exam Above Target. Just make sure you focus your study on the questions you get wrong, rather than the whole.

I have three PMI Credentials: PMP, PMI-ACP, PMI-PBA. I prepared on my own for all of them, no matter I worked in a consulting firm where one of my duties were create and teach preparation courses for those credentials for long time. Just a rule of tumb that worked for me and I saw: when you get systematically 75%-80% or more in the preparation exam questions then you are ready. To be honest, I have no confidence on PM Challenge. I am talking about other sources.

In addition to studying the right content, as mentioned by others, make sure you are studying the right way. By this, I mean that you need to understand your learning style and then use resources that support your learning style.

For example, if you can read a book and not only retain knowledge from the book, but be able to apply it, reading the PMBOK Guide can be a good approach. But, if you don't learn this way, taking this approach will just be frustrating. There are a lot of options for studying - video, audio/podcasts, online courses, boot camps, apps, physical and digital books, flash cards, workbooks, interactive presentations... to name a few. PMI offers tips, including the exam content outline, to help you prepare - https://www.pmi.org/certifications/project...am-preparation.

As far as practice exams go, think of them as both helping you prepare for the exam AND helping you prepare for the questions. The PMP exam is a psychometric test. A quick online search can provide tips for taking psychometric tests.

An important distinction pointed out in a boot camp I once set up for my local chapter is that when you're preparing for the exam, you're not studying to learn new things. You're studying to pass the exam. This may not be completely true when you first start studying, but in the last few months before you take the exam, it should be true. If you're still learning new things in the final month or two before you take the exam, you might not be ready.

PMI's Study Hall was a huge help for me. I only went with the basic version, rather than the plus. I also had a paid subscription to PocketPrep, and had access to Skillsoft through my company.

I had read PMBOK 6 for my CAPM, but like you I read PMBOK 7. I actually read it twice. I also read the Agile Practice Guide twice. After writing my exam, I feel like 7 and the Agile Practice Guides were of more benefit to me, although I would still read 6 to really understand the 49 processes.
