# SSC CGL Math Strategy 2017

Competitive exams are meant for real-men and women. There is no competition for crybabies, kids and for college teens. So first of all, you must get rid of the following “loser” mindsets:

1. Yaar this maths is so hard, I can’t do it.
2. I’m not from science/engineering background hence this is not my cup of tea.
3. I’m poor in maths and I cannot improve.
4. Thik hai, dekh lenge. (alright, I’ll see).
5. I’m from science/engineering background so Math toh dekh lenge.

Maths is not difficult. All it requires is concept clarity + lot of practice. In SSC-CGL exam, you’ve to face Mathematics at two stages.

Stage Maths-Questions Penalty
Tier-I (Prelims) 25 Qs – 100 Marks Negative 0.50
Tier-II (Mains) Paper I: Arithmetical Ability 100 Qs - 200 Marks Negative 0.50

Pillars How ?
1. Conceptual clarity
1. NCERTs
2. Youtube channel study keeda
3. For some topics, directly Quantitative aptitude books.
2. Lot of practice
1. From Quantitative aptitude books.
2. There are lot of books in market, the question is, which one to refer? It is explained at the bottom of this article.

## Getting the conceptual clarity

• We’ll divide Quantitative Aptitude, into topics and further into their types.
•
• Divide every chapter into types that comes in exam and note all type in notebook.
• Firstly cover one topic at one time, then get conceptual-clarity and then solve maximum questions of different types.
• Whenever you learn any shortcut technique, you note it down in your diary and practice same type of questions.
Topic Sub-Topics How to Approach
Number Theory
1. Divisibility, remainders
2. LCM and HCF
3. Unknown numbers from given condition for
4. Fractions-comparisions.
• NCERT Class 7 Chap 2, 9 (fraction)
• NCERT Class 10 Chap 1 (divisibility)
• Finally your Quantitative aptitude
Basic Maths
1. Simplification
• NCERT Class 8 Chap 1
1. Surds, Indices
• NCERT Class 8 Chap 12
• Then NCERT Class 9 Chap 1
1. Roots, Squares, Cubes
• Basics from NCERT Class 8 Chap 6 and 7.
Algebra
1. Linear Equation
• “Mother’s age was x and daughters age..”
• “3 mangos and 5 bananas purchased for…”
• X+1/2x+3=3/8 then find X.
• ^This type of stuff. Just practice and you’ll get a hang of it.
• Basics given in NCERT Class 8 Chap 2 and 9.
• Then NCERT Class 9 Chap 4
• Lastly NCERT Class 10 Chap 3.
1. Quadratic equations, Polynomials
• Factorization and roots. Heavily asked in Tier-II.
• NCERT Class 8 Chap 14
• And then NCERT Class 9 Chap 2
• Lastly NCERT Class 10 Chap 4
Average and Ratios
1. (Mixture Alligations)
• Go through our YouTube channel Study Keeda
1. Simple Average
• Go through our YouTube channel Study Keeda
1. Ratio-Proportion-variations
• For ratio-proportion NCERT Class 8 Chap 13.
1. Partnership
• Go through our YouTube channel Study Keeda
STD
1. Time speed distance
2. Trains, platforms
3. Boats-streams
4. Time and Work
5. Pipes and Cisterns
• Go through our YouTube channel Study Keeda
Geometry
1. Angles, sides, bisectors, circles Etc
• NCERT Class 9 Chap 6, 7, 8 and 10. Quantitative aptitude book.
1. Mensuration (area and volume).
• Basics explained in NCERT Class 8 Chap 3, 11.
• Then NCERT Class 9 Chap 9, 12, 13.
• Lastly Lastly NCERT Class 10 Chap 13
1. Trigonometry
• Understand basics from NCERT Class 10 Chap 8 and 9.
Then exam-oriented concepts from your Quantitative Aptitude book.
%
1. Basic % (increase, decrease in consumption, population)
• Also do NCERT Class 8 Chap 8.
1. Data-interpretation cases.
• Mere extention of % concept. Just practice.
For long division, use this approximation method: Go through our YouTube channel study keeda
1. Profit, loss, discount, marked price.
• Go through our YouTube channel Study Keeda
1. Simple and compound interest rate
• Go through our YouTube channel Study Keeda
Misc.
1. Coordinate Geometry
• SSC has started asking 1-2 questions. So “Koi bhi topic chodna ni h”
1. Progression: Arithmetic+ Geometry
• Again, rarely asked in SSC. Sometimes a question or two comes in the “Reasoning” portion of Tier-I.
• Basically you just have to plug in the values in formulas. Basics of Arithmetic progression explained in NCERT Class 10 Chap 5.
1. Logerithms

## #2: Practice

• Merely knowing the concepts or formulas won’t help. Because unless you practice different variety of questions, you won’t become proficient in applying those concepts flawlessly in the actual-exam.
• Second, despite knowing concept and formulas, people make silly mistakes either in calculation or in plugging the values.
• Third reason- Tier I has 100 questions in 60 limits. = 1.6 minutes per question. Plus, questions reasoning and comprehension might take more than 2 minutes! Therefore speed is essential. Since there is negative marking system, accuracy also matters.
• Practice all previous questions that came in SSC.
• Don thinks I did all many questions and I am Aryabhata now.
• So it is beyond doubt that you have to practice excimer number of questions at home.
• The question is where to get the practice? Which book should be used for SSC exam?
