How to Prepare Quantitative Aptitude for SBI PO Prelims 2017 | Tips, Strategy and Daily Schedule

Hello and welcome to exampundit. To prepare for SBI PO PRELIMS
you need to be smart enough to manage your short time duration and select
your scoring zone.


DI is the most important and Scoring section in quant. Most common
and important pattern are line diagram, bar diagram, pie chart, statement Di ,spiral
Di, triangular Di, Missing Data Di.
To score highly in this section you need to practice a lot so that
you can solve calculations mentally. To understand the problem of the Di, concepts
on Average, Percentage, Ratio, Profit & Loss, Income & Expenditures, Growth
& Population etc. must be clear. You can expect 10-15 questions from Di
& an ordinary student can fetch 10-12 marks easily by proper preparation.
So you first solve all the DI and secure some safe marks.

This is another scoring segment where you need to be strong in
basic calculation. By lots of practice you can learn how to round off or
simplify a value so that we can calculate easily.
You must practice a mix of problems on BODMAS Rule,
Approximations, Square & Cubes, Surds & Indices, Decimals and
Percentages, multiplications of high values .You can expect 5 questions from
this section.

Generally 5 questions are asked on this topic. Either You need to
find a specific term or You need to find the wrong term in the series. To catch
the logic of the series you need to practice every possible types of Number
Series so that you can easily understand the logic of the series. Out of five,
2-3 questions can easily be solved and relatively tougher question should be
left aside without wasting your time.

It is also very scoring & easier section in Quant. you can
score 5 marks within 5 minutes. To do well in this section you must practice
lots of Middle Term factors and build a proper concept on Inequality from any
standard textbook.
It is better to attempt this segment only after finishing the
above mentioned segments in time.
 Important chapters are:
  • Profit &
  • Compound
    & simple interest
  • Speed &
  • Pipe &
  • Work &
  • Age related
  • Problems on
  • Mixtures
    & alligation
  • Probability
    based on permutation & combination
  • Cylinders, cone,
  • Boat &

Apart from these chapters you must study some basic algebra
formulas, basic geometry concepts
are the various chapters you need to practice thoroughly but my suggestion is
first attempt DI, Simplification, quadratic, numbers series & only after
that you have some excess time then go for words problem.
This is less important for preliminary exams & still you can
practice few three statements data sufficiency problems.
Since more than two month is left for SBI prelim exam you must
start your preparation seriously.
All candidates at least give THREE
hours daily on all chapters with special focus on data interpretation. You
must give at least 10-15 full length mock tests from any standard website. Those
who are weak in mathematics need to give four
to five
hours in daily basis with sufficient mock tests. Those who are
working need to give one to two hours
regular practice can enhance your speed to solve calculation quickly. Try to
solve as much as calculation mentally so that you can save times in exam hall.
For all
3 Hours – Daily – All Chapters with special focus on DI
  • 1 hour – Data Interpretation
  • 1 hour – Word Problems, Series, Approximations
  • 1 hour – Quadratic Equations and revise

For weak
4-5 Hours – Daily – All chapters along with Mock Tests (2 mocks)
  • 2 hours – Data Interpretation
  • 2 hours – Rest of the chapters
  • 1 hours – Mock Test

For working
1-2 hours – Daily – All chapters and 1 mock every 3rd
  • 1 hour – Data Interpretation
  • 1 hour – Other chapters
  • On 3rd Day, 1 hour revision and 1 mock

Don’t try to memorize all short cut rules for each kind of problem. Try to
clear basic concepts on every chapters. Note down only the important laws and
formulas and apply those in home.
Formulas of percentage are very useful. If you can remember %
values of few fraction it can save lots of time in DI.As example –
⅛=0.125 ; 1/7=0.1428 so when we will find those values like 12.5%
or 14.28% we can substitute those with ⅛ or 1/7 etc and calculation will be
Apart from that you should remember
squares of up to 30 and Cubes of upto 20.
You must learn rules for finding squares and square root &
cubes and cube root so that you can solve simplification quickly.
In case of number series if you are unable to understand the logic
within 40-45 second just left it and jump to next question.
In DI you may find some question which are almost impossible to
solve in short time. You need to identify
that very fast and avoid the question without wasting any time
In quadratic equation if you are unable to find any factors, Vanishing factors or Shreedharacharya laws
may be used.
In case of simplification problem don’t get puzzled if you found
big values rather be cool and try to find the clues which is needed to solve
the problem.
You must practice probabilities mainly based on combination &
permutation. 2-3 question of this type generally comes in prelim.
Finally best of luck to all those who are starting their preparation.
The way cutoffs are increasing day by day you need to attempt at least 65-70
question in total and in Quant you should attempt 22-25 questions with good
As almost 70 days left for exam practice regularly with full
integration and cover your weak areas.

The entire strategy is prepared by a Bank PO(2015).

All the best!!
