Yes! I passed my PMI PMP exam at first attempt last week! I used the following sources to efficiently use my available time:
1. PMBOK Guide (6th edition): Don't get overwhelmed by the huge pack of pages, try to get the overall process flow first before diving into details
www.pmi.org/pmbok-guide-standards/foundational/pmbok
2. Certification Preparation: Project Management Professional (PMP) at LinkedIn Learning by Sandy Mitchell: Great overview and deep dives!

3. PM PrepCast by Cornelius Fichtner: Must do! Great content while commuting. Also the formula guide and exam questions are a must do!

4. PMBOK Guide Process Flow by Ricardo Vargas: Brilliant overview and concept! This made me clearly understand the process flow and underlying interaction/dependencies

5. PMchallenge questions at ProjectManagement.com: Huge source of materials

Don't be too hard on yourself. An exam is a snapshot. Learning is an ongoing process. Enjoy!
