What they ask

Paper I is an SSLC-level OMR paper: a 100-question Tamil Eligibility Test worth 150 marks, where the minimum is 60, followed by 75 General Studies and 25 aptitude questions worth 150 marks. Paper II is a 200-question computer-based subject paper for 300 marks at diploma or ITI level, for example Civil Engineering for Junior Draughting Officer or Agriculture for Assistant Agricultural Officer. Your rank uses Parts B and C of Paper I plus Paper II, 450 marks in all, and you need 180 (Others) or 135 (reserved categories) to qualify.

How to prepare

  • Paper II carries 300 of the 450 ranking marks, so give most of your time to the subject paper for your diploma or trade.
  • If you are writing the Agriculture paper, four units carry 30 questions each: agronomy and meteorology, soils and fertility management, plant protection, and agricultural extension, economics and digital agriculture.
  • Paper I General Studies uses the same SSLC-level units as TNPSC Group 4, so Group 4 question papers make good practice material.
  • The Tamil Eligibility Test has its own minimum of 60 out of 150; prepare for it early instead of in the final week.
  • Daily topic-wise practice quizzes on the free Improvam app help keep the General Studies and aptitude units fresh while you focus on your subject.
