I used the Knowledge Map to prepare for the PMP certification, before and after the changes in the certification (since 01.01.2022). A very convenient and thorough tool, as it allows you, in the best traditions of project management, to plan your entire path and make a step-by-step preparation schedule, from the application to the date of the exam. Convenient, clear interface, at each stage of preparation according to the schedule. Together with links to specific sections of the PMBOK, the Agile Practice Guide, the schedule has links to additional literature and useful lectures on YouTube. After passing the relevant section, there is an opportunity to purchase an exam on the topic covered. The exam can be taken many times within a month, with questions translated into your native language, which is very convenient. It should be noted that the Knowledge Map allows you to take exams in training mode (the correct answer and explanation of the answer are displayed after each answer to the question) or in testing mode when the result of the exam is displayed after passing it. This option additionally has a time limit for taking the exam, which additionally disciplines and teaches you to monitor time.
As an additional plus, I guess, it is possible to form consolidated information on the dynamics of mastering relevant topics in a detailed breakdown of knowledge areas, process groups, and PMP domains with the display of percentage and quantitative values according to the number of questions and correct answers on exams.
I guess the Knowledge Map is a very effective tool and a serious help on the way to achieving your goal!
