TNPSC How-To Guides
The process side of TNPSC, registration, photos, fees, documents, exam day, explained step by step so nothing gets rejected on a technicality.
Applying
Complete TNPSC One Time Registration in 30 minutes: documents to keep ready, the ₹150 fee, the 48-hour rule, and the mistakes that cost selections later.
From notification to submitted application: eligibility check, OTR login, post preferences, fee payment and the confirmation you must save.
When and how to update OTR details, refresh an aged photo, and what must never mismatch your certificates.
Fee structure, online payment steps, the exemption list, and what to do when a payment fails at the deadline.
Preference order decides your career for years. How to rank posts using salary, promotion lines, transfers and your own constraints.
Documents
The exact TNPSC photo and signature requirements: 3.5×4.5cm photo at 20-50KB, 3.5×1.5cm signature at 10-20KB, 200 DPI, and the rejection reasons to avoid.
The complete certificate verification checklist: education, community, PSTM, category claims, and the mismatches that disqualify candidates.
Getting or renewing the community certificate TNPSC applications depend on: e-Sevai process, documents, timelines and the digital copy.
Claiming the 20% Tamil-medium reservation: who issues the PSTM certificate, the format, and the year-wise proof most candidates miss.
A studio-quality application photo with a phone: the wall, the light, the framing, and resizing to 20-50KB, no photo shop needed.
Exam day & after
Where the hall ticket appears, when it releases, what to check on it, and what to do when it won't download or has an error.
Reporting times, the two things you must carry, everything that's banned in the hall, and the OMR rules that quietly cost marks.
The objection window, what evidence actually works, and how the final key changes results. File it right or don't file at all.
Where results publish, how to read the marks and rank documents, and what the stages after the result actually mean.

Preparation strategy
A Group 4 preparation plan built from the official weightage: Tamil first (100 questions), then the two 20-question GS units, then everything else.
A two-stage Group 2 strategy: clear prelims on breadth, win mains on writing. What changes between stages and what to build from day one.
Group 1 is prelims, descriptive mains and interview. The preparation architecture that survives all three stages, and the timeline it honestly needs.
The Tamil Eligibility Test is half the Group 4 paper. Unit-by-unit tactics for ilakkanam, sollagarathi, the prescribed literature and the 40% trap.
Unit VI carries 20 of 75 GS questions. What actually repeats: Sangam society, Keeladi, Thirukkural themes, the Dravidian movement, and how to prepare each.
Unit V mixes Indian economy basics with Tamil Nadu's schemes and development administration. The split that makes 20 questions predictable.
Polity is the most scoring GS unit after the TN pair: stable facts, article-based questions, no interpretation. How to bank all 15.
Five questions from an everyday-application syllabus. The Samacheer chapters that generate them and the two evenings this unit actually needs.
Five questions, heavily Tamil Nadu-flavoured: rivers, monsoon, soils, districts. Why a map session beats a reading session for this unit.
Indus Valley to independence in 10 questions, with the syllabus naming its favourite leaders. The compression strategy that fits this unit's real size.
25 questions from a deliberately short list: simplification to time-and-work, plus six reasoning types. What to drill and what to refuse to prepare.
Current affairs threads through every GS unit. The daily quarter-hour system, what TNPSC actually asks, and the monthly consolidation that makes it stick.
No new topics, three revision cycles, six mocks. The final-month structure that converts preparation into marks, week by week.
A mock without review is entertainment. The four-way error classification and unit-tracking method that turns each mock into a mark gain.
The recurring first-attempt failures: equal-time preparation, Tamil-paper neglect, PDF hoarding, mock avoidance, and the fixes for each.
Steps and specifications follow official TNPSC instructions and notification annexures. Sources: TNPSC official notifications. Figures are indicative and may change with each official notification. Data last reviewed: July 2026.
