<strong>How I improved my quant story…..</strong>

Hi I am priyanka and this is my story on how I cracked the quant section being a non engineer.

I almost quit preparing for exams when I saw quant for the first time. All my seniors and online articles suggested same that quant is for engineers. My dad was an engineer working at BARC and always wanted me do MBA after I complete my bms. He was not keeping well for some time and stopped going to work as well. So I took up the challenge to swim upstream against the odds to take up competitive exams to keep my dad happy.

Material and tools
I would recommend keeping one coaching classes book as main centre point and a big book like arun sharma or savesh kumar as extra practice. Example I studied percentages from my coaching class book but still need more practice on a particular type of question.. will open savesh kumar and do 10 questions of that type to complete the preparation. Joining coaching classes is individual thing as I feel even after classes u need to study on your own.. unless classes provide shortcuts and strategies avoid them as most of the classes esp famous one just focus on finishing syllabus which you can do at home also.
If you have joined any classes than do solved examples of that chapter before u go for class as it will gives u good understanding of the topic in hand.

Notes and formula book
Make notes of different types of questions as they come across. I made a separate dedicated notebook for quant formulae and used to write everything into it.. this will help you get confidence quickly and ideal way to revise couple of days before exam. Copying or photocopy of other notes won’t help as you wont be able to grasp everything so do some hard work make ur own formula book.

Rotational policy
Trust me quant can be very boring if dont like it. So rotate your topics rather than spending weeks doing one topic. For example I first took up percentages and spent 3 days making head of what’s it’s all about. More than 50% of a chapter for example percentages includes Questions from other areas like geometry ratios etc. Which will make it difficult to understand unless u know everything. To start with only do solved examples and 30 questions per chapter to know devil before you kill it. So spend strictly 1 or 2 days only per chapter considering 20 important chapters, you will be done in 40 days and get some idea about everything of quant. You won’t become expert but will start getting grasp of quant. Will repeat the cycle again (revise first 30 and 30 new questions) again and you will feel confidence seeping in.

Simplify things
In verbal antonym synonyms usage fill in blanks all fall under category of vocab. Similarly there are no 30 different chapters in quant. If you look at from concept point of view there are hardly few types of chapters or concepts.
I feel we can break maths into 6 different categories
Percentages (including profit loss, interest, etc)
Ratios (incl variations, partnerships, time work and time speed)
Geometry ( mensu trigno and coordinate)
Numbers
Algebra
Others (modern maths)
This will help you strategize and plan modules. If you try to do geometry together it will take at least 10 days to complete and you won’t remember most of it. So break into parts doing only 30 questions and moving on.

Practice is key.. thumb rule of 50
I feel minimum of 50 questions are needed to become master of a subject. For example in geometry we have 3 main areas angles triangles and circles so 50 questions of each will be needed to gain confidence. I had quantum cat for savesh kumar and cetking books so took vetting books as reference solved 50 questions first then move to savesh kumar book.
Once you are done with 50 questions of each chapter repeat the cycle to become master.

Weak areas
Once u become scared of a topic it’s gonna kill you remember that. If your weakness is geometry than you are doomed as geometry is gonna haunt you in every exam and make you cry. It happened to me as well. Don’t be shy of asking help, ask any of ur frnds who is doing decent in geometry to help you. Meet him / her and let him teach you. You don’t need too much time 1 to 2 hours is enough for him to teach you the methodology on how to catch the topic and then u can carry on at home. We all need catalyst and some kick starting.. meeting a geometry person will give you positive wibe abt the topic. Don’t leave any topic as weak area. Atleast try 3 times.. tried myself.. in coaching class
… with frnd… still no success than leave it.. will focus on rest of the topics..

Shortcuts
Shortcuts are of two types
1. one cracking question by a shortcut which can only be used to solve this question and
2. Understand from concept level and solve every question in same fashion.
I stumbled upon cetking shortcut on PnC on YouTube and gave it a try it worked for me. I was able to understand and solve question more quickly as I too had difficulty in getting using formulae. Again add every new trick into your formula book.

If you have very less time left for the exam like only 40 days or 30 days dont bother about every chapter and focus on important ones.
Just focus on these 3
Geometry including mensuration
Arithmetic %ages profit loss mixtures averages and
modern maths. Modern maths includes
Logarithm, set theory, AP GP series, PnC, inequality and function graphs.

I was never confident even till last date.. you will be able to solve easy questions but struggle at tough one…that’s normal. I went for my cat exam with nervousness.. I was very happy with my 99.2%ile in quant section. Overall 99.31%ile. It was some kinda satisfaction. Sadly my dad passed away before seeing me joining IIM.

Chalo I will call it off have big company coming on campus tomm for summer intenship. Wish me luck and all the best to you too.
