RRB NTPC 2024 Undergraduate CBT 1 exam (18 August 2025, Shift 1) was of moderate difficulty. It comprised 100 questions worth 100 marks, to be answered in 90 minutes, with 1/3rd negative marking for wrong answers. The paper had three sections — General Awareness, Mathematics, and Reasoning. Reasoning was relatively easier, Mathematics included a few time-consuming problems, and General Awareness tested both current affairs and static GK. Candidates who handled time and accuracy well were able to perform better.
