Should you spend more time studying Science, History, General Tamil or Aptitude for TNPSC Group 4?
When the syllabus covers several subjects, deciding where to begin can be confusing. The TNPSC Group 4 subject-wise weightage helps you understand which sections carry more questions and where to focus your preparation.
The key is to give enough attention to high-weightage subjects without leaving smaller units completely untouched.
Before deciding which subjects to prioritise, review the complete TNPSC Group 4 Syllabus to understand all the prescribed topics and the examination pattern.
TNPSC Group 4 Subject-wise Weightage
The TNPSC Group 4 written examination has 200 objective-type questions for 300 marks. The paper is divided into three sections.
| Subject | Questions | Weightage |
| General Tamil | 100 | 50% |
| General Studies | 75 | 37.5% |
| Aptitude & Mental Ability | 25 | 12.5% |
| Total | 200 | 100% |
General Tamil accounts for half the paper. Candidates must also secure at least 60 out of 150 marks in this section for the remaining part to be evaluated.
This makes Tamil an essential part of daily preparation, even for candidates who are confident in General Studies.
Which General Studies Subjects Have the Highest Weightage?
The General Studies section contains 75 questions across six units.
| General Studies Subject | Questions |
| Indian Economy & Development Administration in Tamil Nadu | 20 |
| Tamil Nadu History, Culture & Socio-Political Movements | 20 |
| Indian Polity | 15 |
| Indian History & National Movement | 10 |
| General Science | 5 |
| Geography | 5 |
| Total | 75 |
Tamil Nadu History and Culture, along with Indian Economy and Development Administration, have the highest individual allocations.
Together with Indian Polity, these subjects account for 55 of the 75 General Studies questions.
What does this mean for preparation?
Students should set aside more revision time for these three areas. However, this is not a reason to ignore Indian History, Science or Geography.
General Tamil: Which Topics Carry More Questions?
General Tamil contains 100 questions divided into seven units.
| General Tamil Topic | Questions |
| Grammar | 25 |
| Vocabulary | 15 |
| Writing Skills | 15 |
| Technical Terms | 10 |
| Reading Comprehension | 15 |
| Translation | 5 |
| Literature, Tamil Scholars & Tamil Service | 15 |
| Total | 100 |
Grammar has the highest allocation, with 25 questions.
Begin with grammar fundamentals and practise vocabulary, sentence correction and reading comprehension regularly.
Literature also deserves attention, particularly the prescribed Thirukkural chapters and contributions of Tamil scholars.
What About Aptitude and Mental Ability?
The Aptitude section contains 25 questions:
Numerical Ability – 15 questions: Percentages, simplification, HCF, LCM, ratio, interest, area, volume, and time and work.
Reasoning – 10 questions: Number series, puzzles, dice, visual reasoning and logical reasoning.
Unlike subjects that involve substantial reading, Aptitude requires repeated problem-solving.
Even 20–30 minutes of regular practice can help candidates build speed and accuracy.
Which Subjects Should You Study First?
Question weightage is useful, but your preparation order should also depend on your strengths and weaknesses.
1. Build a strong General Tamil foundation
Tamil has the largest question allocation and a qualifying requirement. Include grammar, vocabulary and literature in your regular study schedule.
2. Focus on higher-weightage General Studies units
Spend additional time on Tamil Nadu History and Culture, Indian Economy and Development Administration, and Indian Polity.
3. Practise Aptitude consistently
Solve a few numerical and reasoning questions each day instead of leaving the entire section until the end.
4. Cover the remaining General Studies subjects
Include Science, Geography and Indian History in your weekly revision.
These are suggested study priorities based on the syllabus, not an official TNPSC preparation order.
Should You Spend Less Time on Science?
General Science has an allocation of five questions, which is lower than Indian Polity or Tamil Nadu History.
However, skipping Science completely could mean losing marks on questions you might otherwise answer correctly.
For example, if you perform well in Tamil but frequently answer Science questions incorrectly, spend additional time revising basic Physics, Chemistry and Biology concepts.
Your weak subjects matter just as much as the question distribution when planning revision.
How to Divide Four Hours of Daily Study?
Here is a sample timetable for candidates preparing four hours a day.
| Subject | Daily Study Time |
| General Tamil | 1 hour 30 minutes |
| High-weightage General Studies | 1 hour 15 minutes |
| Other General Studies subjects | 45 minutes |
| Aptitude & Mental Ability | 30 minutes |
| Total | 4 hours |
This is an example, not a fixed schedule. Adjust your study time after reviewing your mock-test results.
