Since the 2025 Computer-Based Testing (CBT) recruitment into the Civil Defence, Immigration and Prisons Service Board (CDIPB) began, thousands of Nigerians scheduled for the online exam have been searching for past questions and answers to get a sense of what the test looks like.
In this article, we have compiled a list of past CDCFIB questions and answers to serve as a guide. However, do not rely on these questions, as the Board uses a large database from which questions are randomly selected for each applicant. This means the set of questions for Sandra may differ from those for Adani, and no two applicants will receive the same set of questions.
And one more thing: ensure to read the guidelines of the test before you start, very important, we already put our how to resolve the issues of your session being submitted automatically upon login into the exam room.
