Susan,
My recommendation for students who are re-taking their exam before the end of the month is clear: Take as many sample exams as possible. Practice. Practice. Practice. If you went to a bootcamp then you probably have the knowledge inside of you. The one thing that may be lacking however, is the ability to translate this knowledge to correctly answer questions.
And of course by using the questions in our PMP Exam Simulator (I assume that is what you mean by "questions") you will be able to learn a lot and prepare yourself, give yourself a boost and retake the exam.
