Why Memory Based Questions Matter

Memory based questions (MBQs) are exact or closely-matching questions recalled by candidates based on their exam experience. They serve multiple purposes:

Analyze Exam Difficulty: Compare your attempt with peer-reported difficulty levels.
Identify Important Topics: Spot recurring themes—e.g., certain reasoning puzzles or technical concepts.
Last-Minute Revision: Reinforce concepts by solving questions that appeared in the actual exam.
Mock Simulation: Gauge where you stand relative to actual exam standards.

In the 2025 Re-Exam, over 50 coaching institutes and thousands of aspirants submitted memory based answers soon after exam completion, enabling a rich database of verified questions and solutions.

Exam Pattern & Sectional Breakdown

The RRB JE CBT-2 Re-Exam pattern was identical to the original CBT-2:

Tips to Practice Memory Based Questions Effectively

Review Under Exam Conditions:

Set a timer for 90 minutes and attempt 100 questions (20 reasoning, 15 GK, 65 tech) exactly as per exam pattern.
Simulate negative marking: ⅓ penalty for each wrong answer.

Identify Strong & Weak Areas:

Use your score on MBQs to see which topics you struggled with (e.g., Structural Analysis in Civil, Machine Design in Mechanical, Digital Logic in S&T).
Reinforce weak areas through targeted revision and mock tests.

Create One-Page Revision Notes:

Summarize key formulas (e.g., bending moment, Carnot efficiency) and GK facts (e.g., current Railway Board chairman, recent RRB policy changes).
Keep these at hand for last-minute brush-up.

Group Study for GK Updates:

Divide current affairs topics among peers—each person prepares 5–6 topics (e.g., Gati Shakti, Railway budgets, national policy).
Quiz each other to ensure retention.

Analyze Mistakes Thoroughly:

For every wrong MBQ attempt, write down why you erred (calculation slip, conceptual gap, recall error).
Plan specific drills (e.g., 10 more structural analysis problems if you missed Q1 in Civil).

Regularly Update Memory Bank:

Encourage peers to submit any new MBQs they recall.
Maintain a shared Google Sheet (or local document) to compile questions, answers, and explanations.

Stay Calm & Manage Stress:

Practice short meditation or breathing exercises before mock tests.
During the real exam, avoid spending too much time on any single question—move on and return later.

Frequently Asked Questions (FAQs)

Q1. Are memory based questions exactly from the actual exam?
A1. MBQs are recollections by aspirants and may not be verbatim. However, when multiple candidates report the same question, its accuracy is high. Always cross-verify solutions with trusted sources.

Q2. How reliable are the provided answers?
A2. Answers are verified by experienced faculty and cross-checked against official RRB answer keys (when released). Minor variations in wording may occur, but the core concepts remain correct.

Q3. Can I use these MBQs to predict the cut-off?
A3. While MBQs help assess your performance qualitatively, cut-off depends on overall exam difficulty, total vacancies, and normalization. Use MBQs for practice and refer to our detailed expected cut-off analysis (blog) for estimates.

Q4. Are memory based questions helpful for future RRB JE cycles?
A4. Yes. RRB tends to follow a stable pattern—concepts and question styles repeat. Solving MBQs improves problem-solving speed and gives insight into recurring topics.

Q5. How many MBQs should I attempt in mock tests?
A5. Ideally, attempt all MBQs under timed conditions. If time-constrained, focus first on sections where you are weak (e.g., Tech for Civil/Mec/Elect). Aim for 70–75 attempts with high accuracy.
