u/MemoryTerrible

so i failed the pmp for the 3rd time last year and for a while i decided to just call it quits altogether. i decided last week that i am going to give it another shot and re-apply for the exam. only issue is im not allowed to take it until july. i know that theres a new exam coming up and am wondering if using the same sources (andrew and david m practice questions) are still good? especially for incorporating the mindset?
