Mistakes that cost marks

5 traps seen in the real papers
  • Practising statistics with a calculator. Calculators are banned, so slow hand calculation costs minutes.
  • Skipping accounting. It gave 13 to 17 Paper II questions.
  • Preparing only for the 2025 style. 2022 had 65 numerical problems; APPSC can swing back.
  • Blind guessing. With 1/3 cut per wrong answer, a pure guess gains nothing on average.
  • Ignoring Andhra Pradesh in Paper I. In 2022, 49 of 149 questions were on AP.
