2. Concept Building & Basics

Start by understanding basic concepts of each topic.
Learn formulas, shortcuts, and tricks to solve problems faster.
Work on improving mental calculation for faster simplification.
Solve easy to moderate level questions to build confidence.


How to Approach Basic Topics?
Number System: Learn divisibility rules, unit digits, last two digits, and factorization techniques.
Simplification & Approximation: Master BODMAS, surds, indices, and percentage-based simplifications.
Ratio, Percentage & Profit-Loss: These three topics form the base for multiple arithmetic problems.
Time & Work / Time, Speed & Distance: Focus on LCM-based efficiency methods and relative speed concepts.
Averages & Mixtures: Use alligation methods and weighted averages for quick solutions.
Data Interpretation: Start with simple bar graphs and pie charts before moving to complex caselet DI.

3. Speed & Accuracy Enhancement

Once basic concepts are clear, the next step is to focus on speed and accuracy.

Key Focus Areas:
Practice 50+ simplification and approximation questions daily.
Solve 20-30 questions from arithmetic topics daily.
Work on improving calculations using Vedic Maths tricks.
Set a time limit while solving questions to track speed.
Solve missing and wrong number series questions daily.

Develop shortcut techniques for quadratic equations and DI.
Important Techniques to Improve Speed:
Multiplication Tricks: Use digit-sum techniques for quick calculations.
Percentage to Fraction Conversion: Memorize values for faster problem-solving.
LCM & HCF Shortcuts: Helps in solving time & work, ratio, and partnership problems.
Approximation Methods: Useful for DI and profit-loss problems

4. Advanced Problem Solving & DI Mastery
At this stage, start working on moderate to high-level questions to match the difficulty level of the actual exam.

Focus on:

Advanced DI Sets: Caselet DI, missing DI, and mixed graphs.

Arithmetic-Based DI: Questions combining profit-loss, ratio, and averages with DI.
Probability & Permutation Combination: Learn formula-based approaches and shortcuts.
Mensuration & Geometry: Work on 2D/3D area-volume-based questions.
Data Sufficiency Questions: Develop logical reasoning to solve DS-based quant questions.

How to Attempt Mock Tests Effectively?

Start with sectional tests for Quantitative Aptitude.
Move to full-length mock tests (RRB PO & Clerk).
Analyze mistakes and weak areas after every test.
Keep a formula & tricks notebook for quick revision.
Work on reducing calculation time and increasing accuracy.


Time Management in Exam:
Exam-Day Strategy:
Attempt easy questions first to gain confidence.
Skip lengthy calculations initially and come back later.
Use approximation when necessary to save time.
Stay calm and focused, avoiding guesswork.
