RRB ALP 2025 – Preparation Tips
- Start with CBT 1: Since CBT 1 is qualifying, ensure you clear it first. Focus on Reasoning (25 questions) as it carries the highest weightage.
- NCERT Books for Science: Class 9-10 NCERT Science textbooks cover almost all General Science topics asked in CBT 1.
- Practice Maths Daily: Solve at least 30-50 maths questions daily focusing on speed. Time, Speed & Distance and Ratio & Proportion are high-frequency topics.
- CBT 2 Needs Engineering Focus: The Basic Science & Engineering section in CBT 2 is unique — study from ITI textbooks and basic engineering drawing materials.
- Beware of Negative Marking: Unlike many exams, RRB ALP has 1/3 negative marking. Avoid random guessing — only attempt questions you are reasonably sure about.
- CBAT Practice: Practice aptitude tests for memory, depth perception, and concentration. Railway CBAT simulators are available online.
- Mock Tests Are Essential: Take full-length timed mock tests for both CBT 1 and CBT 2 regularly to build speed and accuracy.
