Sorry to hear that you didn't pass.
The CompTIA style of asking scenario-based questions can get tricky. It sometimes helps to first read the last sentence to see what they're asking, then read the whole text from the beginning to look for clues that will help you choose the "best" answer (or at least help you eliminate some of the possible answers from consideration).
I started learning toward Project+ using this book by Kim Heldman. I see that Amazon has this book of practice questions by Brett Federsen. Going through those could increase your ability to do well on a second try at the exam.
I later decided to aim for a CAPM certification instead of Project+.
If you want to learn CAPM or PMP, I suggest the Udemy course for each by Joseph Philips. He also has a book to learn toward those exams. The style of questions on the CAPM exam may be different than the style used by CompTIA for Project+.
