Study Plan for TNPSC Combined Civil Services-I Examination (Mains)-2020

Syllabus: Covering all the topics in the syllabus is very important. Solve a maximum number of multiple-choice questions for practice. Don't limit yourself to conventional sources. There is plenty of practice material available on the internet - mock tests, sample papers, e-books, video lectures, online study materials, topper notes, etc. Take complete advantage of the digital age!

Making notes: make short notes as you proceed through the syllabus. These notes should be crisp and to the point. Include mind-maps and flowcharts wherever appropriate. Make notes for each chapter highlighting essential details and include a precise explanation of concepts. If you get stuck at any point, search for videos explaining the idea and watch them. Visual aids help you retain information.

Solve previous year papers- Try solving them by having yourself the time limit which you are getting in the examination. The main objective of doing this is that aspirants will identify their weak & strong areas.

Quality Study- It is suggested to not cramp yourself with a massive bulk of study material from multiple sources. This causes you to end up studying nothing instead. Keep your references bounded and knowledge unbounded.
