What is a Computer Based Exam?

A Computer Based Exam (CBT) is a test delivered and taken on a computer, as opposed to a traditional pen-and-paper exam. Candidates sit at an allotted workstation in a designated exam center, log in with a unique credential, and answer questions displayed on screen — typically multiple-choice, though some exams also include descriptive, coding, or drag-and-drop style questions.

Why agencies moved to CBT

• Faster result processing since answers are captured digitally.
• Ability to run multiple shifts with different, randomized question sets, reducing mass paper leaks.
• Built-in timers, auto-submission, and reduced manual errors in evaluation.
• Easier to scale to lakhs of candidates across many cities simultaneously.
• Detailed digital logs of every action, useful for audits and dispute resolution.

Typical exam-day flow

Candidates usually arrive early for document and biometric verification, are allotted a specific system, complete a short tutorial or mock screen, then begin the timed test. Rough work sheets are provided separately and collected at the end; nothing may be taken out of the exam hall.
