My DI LR is not strong . What should I do ?

Data Interpretation and Logical Reasoning needs to be practised as much as possible. Comparison of data, Data Analysis, taking clues, interpreting missing data, coming to conclusions and making future projections will be covered under this Category. The questions here are interlinked and so if you get one formula correct, cracking the next few questions will be easy. So it's important to memorise and practise formulae. You should cover topics like Data tables, Data Charts, Bar Diagrams, Pie Charts, Graphs, Data Comparison and Analysis.

Preparation tips:

As this is the most tricky section, this needs a lot of practise. Solve as many sample papers as possible to get the hang of the section. Make notes when required. Regular practise can help you understand and solve the questions easily as time goes on.

Overall,once you know the syllabus, it's easier from there on.Go through the previous papers to analyse and prepare a comprehensive plan and set priorities according to the importance of different topics across sections. Customise your own study plan based on your strengths and weaknesses. Gauge your preparation from time to time by taking mock tests. Solve questions to check your levels of preparation but not to set any targets. Remember, its ok to have cheat days and relax. But make sure you have a plan and stick to it for the next few months
