RRB JE CBT2 Exam Pattern
RRB JE CBT 2 exam will have 150 multiple-choice questions (MCQs) and each question will be 1 mark. The subjects included in the exam are General Awareness, Physics and Chemistry, Basics of Computers and Applications, Basics of Environment and Pollution Control, and Technical Abilities, To pass the exam, you need to score at least 40% marks. The exam duration is 2 hours (120 minutes). For each wrong answer, 1/3rd of a mark will be deducted as negative marking. Non-Technical section is common for all the branches.
