**How to maximize performance in the DI-LR section?**

CAT has made things different! A full fledged DI-LR section – with a fixed time of 60 minutes – This is NEW! Earlier, even in the days of mid 2000 CAT papers, DI goodies used to do more of DI, while the DI absconders used to focus just to clear the cut off in the DI-LR section. Fixed time and a separate section – means we need to have more clarity on the section.

Lets prepare this section well - with more focus than ever before in our road to CAT 15. Remember, DI-LR has been the favorite of all CAT aspirants - typically both engineers and non-engineering graduates. By separating it, CAT has made the equations interesting - REAL CONTEST now! ~~~ REAL fun now! Lets understand :)

Number of questions: 32. Expect 8 sets of 4 questions each. A healthy score of 95 percentile + should not be more than 45% marks which means 15-17 questions correct with no mistakes – Ideally there is always a risk of getting 1-2 questions wrong due to the high speed requirements of the exam. Hence, something like 19-20 attempts with 1-3 wrong should be a good bet for clearing the sectional cut-off for the top IIMs – this is assuming the same pattern and level of DI-LR as it used to be in the last 3-4 years of paper based CAT i.e CAT 2005-2008.

Now, this means we are looking at solving 5-6 sets of 4 questions – This in turn implies that we should be able to crack different types of sets with confidence. The first level thing is to be familiar with the different types of concepts that come normally in MBA entrances – Let me list down the 15 most important ones for this year CAT.

The first level thing is to be familiar with the different types of concepts that come normally in MBA entrances – Let me list down the 15 most important ones for this year CAT.

1. Pie Chart mixed with table or pie or pie with a sub pie.

2. Bar Graph – single, stacked, cumulative – vertical or horizontal

3. Line Graph – single, multiple, stacked

4. Tabular DI – observation based, missing data based, secondary data creation(this means creating data from the given data sets and then use observation or calculations) based – less approximation or first level ratio comparison based.

5. Tournaments

6. Syllogism – still less chance

7. Data Sufficiency

8. Group Formation - those team formation problems!

9. Ordering and Sequencing - apartment floors, sequence of guests etc.

10. Truth, False, Binary Logic

11. Blood relation – less chance

12. Sitting Arrangement

13. Input/Output problems – less chance though

14. Mileage/ Transportation/ Shortest path/Direction sense problems

15. Constraint based/ Optimization problems

**LEVEL 1 PREPARATION:**Solve atleast 4-5 sets on each of these topics – make sure you are ready with the basics of each of these types.

**LEVEL 2 PREPARATION:**Bundle the CAT-XAT questions of the last 20 years into these topics – Now solve these topic buckets – one every day! This will make you super confident when you see any of these types in the exam hall.

Be smart in selecting the sets you are going to solve first. Refer to the diagram below to understand the psychology of when to enter a set and when to leave it. Do not spend much time in getting stuck with any data set or direction set – If not clear, leave and move on! There are many questions to be solved – not all though – You can leave some!

**Few tips for the DI-LR section:-**

1.

**Do not overuse the calculator**:- Not for simple multiplication like 12*13 = 156 – Common, this has to be done in no time. Practice hard.

2. Do not take lots of thinking time in

**generating second level data**. For example: -

First thing that should strike here is this second level table: Be quick to do all this.

3.

Pie chart has 360 degree which is equivalent to 100 percentage which is in turn equivalent to the absolute number which can be equated to the total fractional share as 1. Now, these things should be strong and clear. You should know what stacked graphs mean – what cumulative graphs mean and what it means to find out CAGR. Basically, be in good practice.

**Feel free to flush in the missing data**–with the calculators there, they might ask you to fill more and more data. MISSING DATA EXAMPLE SET:-For example, see this data set – it’s a simple example where you might be expected to fill in the blanks for the questions that follow!

5. Also, do make sure that

6. Practice Sudokus and lateral

7. Give

Keep solving, Best Wishes!

5. Also, do make sure that

**solve ARITHMETIC**(Specially percentages, averages ratio proportion, profit and loss, interests) well in your QA Prep – this will help u a lot in DI too.6. Practice Sudokus and lateral

**thinking puzzles**too! Reasoning times are back!!7. Give

**DI-LR tests**and revise them multiple time. CAT classic sets of QA-DI like Beizing Olympic, Erdos Number, Naya Purana etc – solve them as many times as needed to make concepts sink into your grey cells.Keep solving, Best Wishes!
