Intro to SSC CGL Maths

Competitive exams are meant for real-men and women. This is no country for crybabies, kids, college teensand no0bs. So first of all, you must get rid of the following loser mindsets:

1. Yaar this maths is so hard, I cant do it.

2. Im not from science/engineering background hence this is not my cup of tea.

3. Im poor in maths and I cannot improve.

4. Thik hai, dekh lenge. (alright, Ill see).

Maths is not difficult. All it requires is concept clarity + lot of practice. In SSC-CGL exam, youve toface Mathematics at two stages

Stage Maths-Questions Penalty

Tier-I (Prelims) 50 Qs Negative 0.25

Tier-II (Mains) Paper I: Arithmetical Ability 100 Qs worth 200 marks Negative 0.50

The Approach for Maths, stands on two pillars.

Pillars How?

1. Conceptualclarity

1. NCERTs (Free download links @bottom)2. Mrunal.org/aptitude3. For some topics, directly Quantitative aptitude books.

2. Lot ofpractice

From Quantitative aptitude books.There are lot of books in market, the question is, which one to refer? It is

explained at the bottom of this article.

#1: Getting the conceptual clarity

Well divide Maths or Quantitative Aptitude, into topics and further into subtopics.

Your task is to cover one topic at a time, first get conceptual-clarity and then solve maximumquestions at home.

Whenever you learn any shortcut technique, you note it down in your diary.

Similarly, whenever you make any mistake while solving sums, you also note that down in your diary.Night before the exam, you review that diary of mistakes. (why do this? Because it is the Art ofAptitude (Click ME)

Simple andcompound interestrate

http://mrunal.org/2012/04/aptitude-compound-interest-rate.html

PCP 1. Permutation2. Combination3. Probability

Not asked as such.But Sometimes a question or two comes in the

Reasoning portion of Tier-I. Hence not muchattention necessary.

But again, they too can be solved without mugging upformulas: go through various articles onwww.Mrunal.org/aptitude

Misc. 1. CoordinateGeometry

Lately SSC has started asking 1-2 question in eachof Tier I and II. But they can be solved by merelyplugging numbers in the readymade formulas given inyour Quantitative Aptitude book.

2. Progression:Arithmetic+Geometry

Again, rarely asked in SSC. Sometimes a question ortwo comes in the Reasoning portion of Tier-I.

Basically you just have to plug in the values informulas. Basics of Arithmetic progression explained inNCERT Class 10 Chap 5.

3. LogerithmsNot asked.

Breakup: SSC-CGL Tier I (2010, 2011, 2012)

Topic 2010 2011 2012

Ratio+Partnership 3 3 1

number theory 6 5 2

Avg+alligation 3 3 2

TSD 6 5 2

Misc. 3 0 2

basic math 11 11 5

algebra 6 0 5

DI 3 4 5

% 6 14 5

Trigonometry 0 0 9

Geometry 3 5 12

Total 50 50 50

The 2012s Tier-I paper, is trend-breaker. Because

1. The conventional questionsfrom ratio-proportion, basicmaths, time-speed-work areasked for namesake only.

2. Otherwise, Out of 50 Mathsquestions in tier-I, almost 30questions are from just Geometry+Trig+Percentage application.

3. Earlier, they used to ask mostly area-volume-perimeter type questions from Geometry segment. Youjust had to plug-in values into the formulas and get the answer.

4. But This 2012s paper has mostly theory based geometry (angle, bisector, tangent, inequality oftriangles etc.)

5. Similarly the difficulty level of algebra, number theory based questions is bit raised.

Or perhaps SSC too decided to employ the BackbreakingTM move of UPSC! Anyways, jokes apart, the lessonhere is, adapt.

Breakup: SSC-CGL Tier II (2010, 2011, 2012)

Type 2010 2011 2012

basic math 11 4 3

Misc. 2 2 3

Trigonometry 0 4 8

Algebra 10 13 10

% 27 18 19

Geometry 14 10 27

Total 100 100 100

Here too, Geometry+Trigonometry have been given emphasis like never before.

Almost 65% of the paper is made up of Geometry, Trig, Percentage and Algebra (and in that too,mostly Quadratic equations.)

#2: Practice

Merely knowing the concepts or formulas wont help. Because unless you practice different variety ofquestions, you wont 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 inpluging the values.

Third reason- Tier I has 200 questions in 120 limits. =not even 2 minutes per question. Plus,questions reasoning and comprehension might take more than 5 minutes! Therefore speed is essential.Since there is negative marking system, accuracy also matters.

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?

Choice of Quantitative Aptitude Book?

In all competitive exams, uncertainity factor is involved. Despite your best preparation, you mightlose the success-train by 2-3 marks.

Therefore you must never put all eggs in one basket.

While you are preparing for SSC, you should also keep open mind and apply for other competitiveexams, such as IBPS, ACIO, ONGC, Railways, LIC, CDS, Coast Guard etc. (Depending on your career-taste).

Publication houses will come up with new books for each and every of t^hese exams, but we haveneither the time nor the money to buy a new book for every new exam.

Such readymade books are only skimmed down version of original topicbooks. For example, if there is

SSC-FCI exam, or ACIO exam, these people will combine a few topics of GK, maths, reasoning andenglish. And present you a book.

Problem= you dont get comprehensive understanding or coverage. Besides, given the population ofIndia, competition level is always high, irrespective of exam. So half-hearted preparations withreadymade condensed books dont help much.

Almost all of these exams follow same structure:

1. General awareness

2. Maths

3. Reasoning (Verbal, Non-Verbal)

4. English vocabularly, grammar and comprehension.

How do they differ from each other?= number of questions, difficulty level and inclusion / exclusion ofparticular subtopics.

So when youre picking up books for the first time, you should choose the books, that have universalusefulness for similar exams. That way your time, effort and money will be saved.

Books for Maths/Quantitative Aptitude

DONOT use Quantitative Aptitude by R.S.Agarwal for SSC-CGL.

Problems with RS Agarwals Math book:

1. The way SSC-CGL question pattern is transforming, R.S.Agarwals book on Quantitative aptitude, is justnot upto the mark to match this changing environment.

2. Its chapter on Trigonometry (Height and Distance) is simply insufficient to handle SSC-CGL levelbombarding.

3. Similarly coverage of algebra, quadratic equations and number theory is either absent or just fornamesake.

4. Geometry coverage is mostly confined to area-volume-perimeter (=mensuration). But SSC-CGL ismoving towards Non-mensuration geometry (angle, bisectors, midpoint, circles, triangles etc.)

5. The printing and presentation is very cluttered. He has written the book assuming that you werealready good at maths from school level.

6. If youre already good at basic concepts, use this book for practicing and improving your speed, elsedont bother, there are better books in market.

Pricing factor

The point is, both books of Arihant Publication (Sarvesh or Rajesh) are way better than R.S.Agarwal,in terms of content, presentation, language and coverage, without being too expensive thanR.S.Agarwals book.

And both of them have universal application for almost all of the competitive exams in India (for mathssegment).

My advice, go with either Rajesh Verma or Sarvesh Kumar. Then the question, which one to pick up?

Fast Track ObjectiveArithmetic by Rajesh Verma.

Quantam CAT by Sarvesh Kumar

The size and price factor goesin favor of this book.

Concepts, techqniues,readymade formulas given hereand there. Language,presentation is lucid.

Algebra, quadratic equationand Trigonometry specificchapters are given for exclusivelyfor SSC.

If you solve all the sums of thisbook, then mathematics portionof SSC-CGL (Tier-I and II) will beas easy as a walk in the park.

Although book is written for CAT and Managementexams, he starts explaining everything from basics.Then exercises are divided into Introductory

IBPS, UGC, LIC, CDS etc. levelexams, its utility starts diminishingas you move towards higher-endexams.

Permutation-Combination-Probability coverage isThorough. (Hell even more sums than ArunSharmas).

This make it ideal text-book for CAT/CMAT andother higher end exams.

B^ut merely getting either of these books, is not going to make you a topper.

If you want to become truly invincible for the maths portion of any competitive exam, then you must practicemaximum numbers of questions at home and maintain a diary of mistakes.

This concludes how to approach Mathematics/Quantiative Aptitude for SSC-CGL exam.

Now only two topics remain (will be discussed later, in separate articles):

1. How to approach Logical Reasoning

2. How to approach English vocabulary, grammar and comprehension
