TIFR GS Exam Important Chapters Based on Previous-Year Papers

Previous year papers are the main source to identify TIFR GS high-weightage topics. There are a few ways in which we can use TIFR GS previous year papers.

• We can use them as exam papers to practice and create an exam-like environment at home.

• We can understand the TIFR GS 2027 syllabus and important topics after reviewing the papers.

• We can also identify what topics are omitted or added in the syllabus of the previous year's papers.

TIFR GS 2027 Syllabus and Important Topics

Students should check the syllabus before starting preparation for the TIFR GS exam. All the syllabi of each subject has been given in the table below.

We have separated the chapters into three parts as per their importance. Students can check the following table for more information.

There should be different strategies for different subjects as not everyone has the same knowledge about all the subjects. So, preparing a routine incorporating all the subjects in it as per your strengths and weaknesses, is an essential thing.

• For maths, if your base is strong, then practice more and strengthen important chapters such as Calculus, coordinate geometry, probability, etc.

• For chemistry, focus more on formulas, periodic tables, and physical and chemical chemistry.

• For physics, many theories and formulas are important, as calculation based questions appear in the exam as much as theory based questions.

• Biology is generally less tough than the above three. Focus more on the textbook and notes to prepare for it.
