TNPSC Combined Technical Services Syllabus

The TNPSC Combined Technical Services syllabus has a Paper I common core and a Paper II subject that depends on your post. Paper I covers Tamil Eligibility, General Studies, and Aptitude and Mental Ability. The subject standard for Paper II may be degree, postgraduate, diploma or trade level according to the notification and code.

Use the official TNPSC question paper archive to confirm subject names and see the types of questions asked. Look up the exact code from the notice rather than using the name alone. Civil Engineering 398 and Civil Engineering 443, for example, appear in different 2026 streams and lead to different preparation material.

Plan the three parts of Paper I

Keep Tamil eligibility scores separate from your ranking-score practice. Use short comprehension and grammar drills to improve reliability, then measure performance against the threshold applicable to your notice. When you review a Tamil question, write the rule in your own words and test it on an unseen example.

For General Studies, use the notified syllabus units to organise material such as history, polity, economy, science and Tamil Nadu topics. For Aptitude and Mental Ability, build speed only after you can reliably identify the method. Use a short calculation log for unit conversions and a separate reasoning log for the conditions you repeatedly overlook.

Find the Paper II code and standard

A qualification name and an exam paper name need not be identical. Keep a row with notification number, post code, subject code, standard and format. Then check the syllabus annexure for unit headings and any indicative weightings. The 2026 Interview scheme and syllabus explains that unit distributions can vary. Use those figures for planning rather than assuming every paper will contain an exact quota.

Combine common and specialist revision

1. Build the map. Save the syllabus and addenda for your notice. Write the Paper I and Paper II codes on your first page.

2. Study in pairs. Pair short Paper I retrieval with deeper technical practice, such as a labelled drawing, a worked problem or a trade procedure.

3. Use official questions. Try a paper bearing the correct code and review weak units before repeating a timed set.

4. Track the interview separately. If your stream includes it, practise explaining relevant experience and technical decisions in your own words.

The TNPSC CTS exam pattern guide helps you select the right timing, while the study notes guide shows how to organise material by code. On Testkart, compare a sample with the notified unit and standard before choosing a resource. Use Testkart practice or your own sets to check whether a technical topic still causes mistakes after revision.
