Key Points at a Glance

  1. 1

    The 2026 Senior Secondary CET reasoning syllabus directly includes Blood Relation, Code and Decode, Sitting arrangement, and Mental ability and analytical ability; keep practice anchored to these listed areas.

  2. 2

    In blood relation questions, separate generation, gender and marital link before deciding the final relation; never assume a person's gender unless the statement fixes it.

  3. 3

    In code-decode questions, identify whether the rule changes letters, positions, numbers, word order or symbols, and test the rule on more than one part of the example.

  4. 4

    In linear sitting arrangement, left and right depend on the direction in which the persons are facing; immediate left/right means the adjacent seat only.

  5. 5

    In circular sitting arrangement, facing the centre and facing outside reverse the left-right reading, so mark the facing direction before placing neighbours.

  6. 6

    In analytical reasoning, convert each sentence into a constraint, place fixed information first, and keep tentative possibilities separate from confirmed facts.

  7. 7

    Negative clues such as “not on Monday” or “does not sit next to” are as important as positive clues because they eliminate impossible positions.

  8. 8

    When a question gives two possible branches, carry both briefly until one contradicts a condition; do not force a single branch too early.

  9. 9

    Before marking the option, recheck the chosen answer against every condition, because one ignored condition can make an otherwise neat arrangement wrong.

Syllabus fit and core approach

For CET Senior Secondary Level, this lesson should be read as part of the Logical Reasoning and Mathematics block. The current official list directly names Blood Relation, Code and Decode, Sitting arrangement, and Mental ability and analytical ability. That means the useful focus is not abstract logic for its own sake, but short exam problems where given conditions must be converted into a clean diagram, table or code rule.

The common method is simple. First, identify what type of information the question gives: family links, seating positions, coded letters or mixed conditions. Second, write only what the statements force. Third, test every option against the written conditions instead of relying on a mental impression. In this paper, many wrong options look reasonable because they match one clue while quietly breaking another.

Exam discipline: treat each sentence as a constraint. A constraint is stronger than a guess and weaker than outside knowledge. If a fact is not written in the question, do not add it.
