The Paper-Based Test (PBT) remains the standard format for NAT-TEST sessions in Bangladesh. For PBT sessions, candidates must use HB pencils and erasers to mark their answers on specialized optical mark recognition (OMR) sheets. It is essential to fill the bubbles completely and clearly to ensure accurate scoring. Seat plans and admit cards are released a few days before the test date, and candidates are advised to visit their designated venue ahead of time to familiarize themselves with the location.
