introduction
Competitive exams are meant for realmen and women. This is no country for crybabies, kids, college teens and no0bs. So first of all, you must get rid of the following “loser” mindsets:
 Yaar this maths is so hard, I can’t do it.
 I’m not from science/engineering background hence this is not my cup of tea.
 I’m poor in maths and I cannot improve.
 Thik hai, dekh lenge. (alright, I’ll see).
 Maths is not difficult. All it requires is concept clarity + lot of practice. In SSCCGL exam, you’ve to face Mathematics at two stages
Stage  MathsQuestions  Penalty 
TierI (Prelims)  50 Qs  Negative 0.25 
TierII (Mains) Paper I: Arithmetical Ability  100 Qs worth 200 marks  Negative 0.50 
 The Approach for Maths, stands on two pillars.
Pillars 
How? 




#1: Getting the conceptual clarity
 We’ll divide Maths or Quantitative Aptitude, into topics and further into subtopics.
 Your task is to cover one topic at a time, first get conceptualclarity and then solve maximum questions 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 of Aptitude” (Click ME)
Topic  Subtopics  How to approach 
Number theory 


Basic Maths 








Algebra 





Avg and Ratios 

Can be solved without formula. Go through https://mrunal.org/2012/03/aptitudealligationsmixturesalloys.html 

Lolz  

For ratioproportion NCERT Class 8 Chap 13.  

https://mrunal.org/2012/05/aptitudepartnershipandprofitsharing.html  
STD 

All of them can be solved with just one Universal STD formula. Explained in www.Mrunal.org/aptitude 
Geometry 






Understand basics from NCERT Class 10 Chap 8 and 9. Then examoriented concepts from your Quantitative Aptitude book.  
% 

Also do NCERT Class 8 Chap 8. 

Mere extention of % concept. Just practice. For long division, use this approximation method: https://mrunal.org/2012/11/aptitudelongdivisiontwodigitdivisioncalculationwithouttearsandwithoutboringvedicspeedmaths.html

The 2012’s TierI paper, is “trendbreaker”. Because
 The conventional questions from ratioproportion, basic maths, timespeedwork are asked for namesake only.
 Otherwise, Out of 50 Maths questions in tierI, almost 30 questions are from just Geometry+Trig+Percentage application.
 Earlier, they used to ask mostly areavolumeperimeter type questions from Geometry segment. You just had to plugin values into the formulas and get the answer.
 But This 2012’s paper has mostly theory based geometry (angle, bisector, tangent, inequality of triangles etc.)
 Similarly the difficulty level of algebra, number theory based questions is bit raised.
Or perhaps SSC too decided to employ the Backbreaking^{TM} move of UPSC! Anyways, jokes apart, the lesson here is, “adapt.”

 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 won’t help. Because unless you practice different variety of questions, you won’t become proficient in applying those concepts flawlessly in the actualexam.
 Second, despite knowing concept and formulas, people make silly mistakes either in calculation or in pluging 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 might lose the successtrain by 23 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 competitive exams, such as IBPS, ACIO, ONGC, Railways, LIC, CDS, Coast Guard etc. (Depending on your careertaste).
 Publication houses will come up with new books for each and every of ^these exams, but we have neither 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 SSCFCI exam, or ACIO exam, these people will combine a few topics of GK, maths, reasoning and english. And present you a book.
 Problem= you don’t get comprehensive understanding or coverage. Besides, given the population of India, competition level is always high, irrespective of exam. So halfhearted preparations with readymade “condensed” books don’t help much.
Almost all of these exams follow same structure:
 General awareness
 Maths
 Reasoning (Verbal, NonVerbal)
 English vocabularly, grammar and comprehension.
 How do they differ from each other?= number of questions, difficulty level and inclusion / exclusion of particular subtopics.
 So when you’re picking up books for the first time, you should choose the books, that have universal usefulness 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 SSCCGL.
Problems with RS Agarwal’s Math book:
 The way SSCCGL question pattern is transforming, R.S.Agarwal’s book on Quantitative aptitude, is just not ‘upto the mark’ to match this changing environment.
 Its chapter on Trigonometry (Height and Distance) is simply insufficient to handle SSCCGL level bombarding.
 Similarly coverage of algebra, quadratic equations and number theory is either absent or just for namesake.
 Geometry coverage is mostly confined to areavolumeperimeter (=mensuration). But SSCCGL is moving towards Nonmensuration geometry (angle, bisectors, midpoint, circles, triangles etc.)
 The printing and presentation is very “ cluttered”. He has written the book assuming that you were already good at maths from school level.
 If you’re already good at basic concepts, use this book for practicing and improving your speed, else don’t bother, there are better books in market.
Pricing factor
Author  
Quantitative Aptitude For Competitive Examinations (S.Chand) 
R.S.Agarwal 
Quantum CAT (Arihant) 
Sarvesh Kumar 
Fast Track Objective Arithmetic (Arihant)  Rajesh Verma 
 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 than R.S.Agarwal’s book.
 And both of them have universal application for almost all of the competitive exams in India (for maths segment).
 My advice, go with either Rajesh Verma or Sarvesh Kumar. Then the question, which one to pick up?
Fast Track Objective Arithmetic by Rajesh Verma. 
Quantam CAT by Sarvesh Kumar 




^But 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 practice maximum numbers of questions at home and maintain a “diary of mistakes”.
This concludes how to approach Mathematics/Quantiative Aptitude for SSCCGL exam.
Now only two topics remain (will be discussed later, in separate articles):
 How to approach Logical Reasoning
 How to approach English vocabulary, grammar and comprehension
