Think and Practice is the main stretch to get well score in this section. Above all this you should go through previous years questions and get an idea of pattern and level of questions been asked in previous CAT papers.

Different types of LR Sets:
Arrangements (Linear and Circular)
Tournament & Games
Sequencing & Ranking
Selection
Networks & Routes
Cubes & Venn Diagrams
Puzzles
Do not be afraid of solving complicated DI and LR sets. You need to continuously challenge yourself and solve as many advanced level problems as possible.
Practice sectional mocks and analyse them to understand the concepts clearly.

Do good time management and do not get stuck on individual questions. Attempt the case questions somewhere in between – i.e. not at the start and neither at end because you may get stuck at the start and find it a problem moving forward and since they require around 5-10 minutes, doing it at last can be an issue for nervous chaps.

Good Luck!!
