What the 25 Sep 2025 Shift 2 Reasoning paper tests

Useful rules for the series and number questions

• \( n \)th term of an arithmetic series: \( a_{n}=a+(n-1)d \)
• Sum of the first \( n \) odd numbers: \( 1+3+\dots+(2n-1)=n^{2} \)
• Perfect cubes: \( 2^{3}=8,\ 3^{3}=27,\ 4^{3}=64,\ 5^{3}=125 \)

Revision tips for SSC CGL Reasoning

• Memorise the position number of every letter from A to Z, forwards and backwards, so that coding and letter series questions take seconds
• In inequality questions, link two terms only through a common term and check whether the signs point the same way
• For floor puzzles, place the fixed clues first and then test the remaining options against each condition
• Learn the four prime digits (two, three, five and seven) to handle number-property questions quickly
