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. 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. Focus on Puzzles, Seating Arrangement, Logical Sequences, Number Test, Verbal reasoning, Family/relations/Ranking and Order, Coding and Decoding.
