RRB Isolated Categories Syllabus 2026: Railway Recruitment Boards (RRBs) have released the official selection process, exam pattern and post-wise syllabus for the Isolated Categories Recruitment under CEN No. 09/2026 for 191 vacancies. The selection will be done through a single stage Computer Based Test (CBT) of 100 marks, a qualifying Translation Test for Junior Translator (Hindi), followed by Document Verification and Medical Examination. Half of the CBT (50 marks) is post-specific Professional Ability, so the syllabus is different for each post.
Since the professional section carries the most weight, candidates should focus on the subject syllabus of their own post given below, while preparing General Awareness, Reasoning, Maths and General Science together. There is negative marking of 1/3 mark for every wrong answer, so attempt questions carefully.
