Key Points at a Glance

  1. 1

    Use only the Graduation Level 2026 Logical Reasoning and Mathematics bullets for this topic: number series, alphabet series, clock, calendar, blood relations, and mental/analytical ability.

  2. 2

    Number series should be tested through differences, second differences, multiplication, square and cube patterns, prime/composite patterns, alternating positions, and mixed operations.

  3. 3

    Alphabet series should first be read visually; convert letters to position values only when the jump, reverse order, mirror relation, or paired movement is not clear.

  4. 4

    Calendar questions are odd-day problems: common years add 1 odd day, leap years add 2 odd days, and completed months before the target date must be counted accurately.

  5. 5

    The Gregorian leap-year rule is divisible by 4, except century years unless divisible by 400; this is the safest way to test years such as 1900, 2000, and 2100.

  6. 6

    Clock-angle questions are relative-speed questions: the minute hand moves 6 degrees per minute, the hour hand moves 0.5 degree per minute, and their relative speed is 5.5 degrees per minute.

Current Syllabus Boundary

This topic has been rebuilt for the CET Graduation Level 2026 syllabus, not the older reasoning list. The relevant official Graduation Level block is Logical Reasoning and Mathematics, and the in-scope reasoning bullets used here are: Blood relations; Number series; Alphabet series; Clock; Calendar; Mental ability and analytical ability. Older reasoning areas that are not listed in this Graduation Level 2026 block are left out of the teaching surface, so the lesson stays tied to the current syllabus. The safe exam approach is therefore narrower and cleaner: learn how a sequence changes, how dates accumulate odd days, how clock hands move, and how a small relation or analytical clue is represented. The topic still trains reasoning, but every method is tied to a listed syllabus item. When a practice question looks like an old mixed-reasoning question, first ask which current bullet it actually tests. If it tests number series, alphabet series, clock, calendar, blood relation, or general analytical ability, solve it. If it depends mainly on a dropped legacy pattern, do not let it drive revision time for this topic.
