Joy, if you decide to invest in a bootcamp, you should consider the source of the education. The provider should be following PMBOK 5th Edition and it should be listed as a PMI.org accredited course, as designated by the acronym R.E.P. This will give you the assurance you are getting the correct curriculum training. Now of course, education is about the teachers and students alike, so I would research what the organization is that is conducting the training and seek others who used it for their opinion about the quality of instruction. My recommendation is you seek a local PMI chapter because they often sponsor PMP preparation courses or can tell you about reputable ones in the area.
