Paper A (Indian Language, 300 marks) and Paper B (English, 300 marks) are both qualifying papers — you need 25% (75/300) in each. Neither counts toward your merit rank. Paper A exemption applies to candidates from six North-Eastern states.

Paper A — Indian Language: Full Details

Qualifying marks: 75 out of 300 (25%). This threshold is absolute — there is no grace, and there is no relaxation for SC/ST/OBC/PwBD candidates on qualifying papers.

Language options for Paper A: Candidates choose one from the 22 Eighth Schedule languages listed below:

Assamese, Bengali, Bodo, Dogri, Gujarati, Hindi, Kannada, Kashmiri, Konkani, Maithili, Malayalam, Manipuri (Meitei), Marathi, Nepali, Odia, Punjabi, Sanskrit, Santali, Sindhi, Tamil, Telugu, Urdu

Key: The language chosen for Paper A does not have to match your Mains medium. A candidate writing GS in English can choose Tamil for Paper A.

Paper B — English: Full Details

Who must appear: Every single UPSC Mains candidate, without exception. There is no state-based or background-based exemption from Paper B.

Qualifying marks: 75/300 (25%). Same absolute threshold as Paper A.

Paper B Structure: Mirrors Paper A in format — Essay, Comprehension, Précis, Translation (Indian language to English and reverse), Grammar. The level tested is approximately Class 10–12 standard English proficiency.

Critical consequence: If you fail Paper B, none of your GS Papers or Optional papers are evaluated. You are effectively disqualified from Mains, regardless of how well you wrote other papers. This applies to every candidate including those writing GS in Hindi or regional languages.

North-East State Exemption from Paper A

Candidates whose home state's official language is not on the Eighth Schedule are exempted from Paper A. The six states are:

StateReason for exemption
Arunachal PradeshMultiple tribal languages; no single Eighth Schedule option
ManipurManipuri is on the schedule, but the state has many non-schedule tribal communities — exemption applies to Meitei and non-Meitei candidates alike
MeghalayaOfficial state language (English) not on Eighth Schedule
MizoramOfficial state language (Mizo) not on Eighth Schedule
NagalandOfficial state language (English) not on Eighth Schedule
SikkimNo single Eighth Schedule language serves as state-wide first language

These candidates still must appear for Paper B (English) — there is no exemption from that.

Common Mistakes Candidates Make on Paper A and B

MistakeConsequence
Treating Paper A as trivial because it is 'only qualifying'Candidates have been disqualified scoring 60–70/300; 75 is not automatic
Not preparing for Translation sectionsTranslation (40 marks) requires specific practice; casual preparation fails
Choosing an obscure Eighth Schedule language for Paper A without proficiencyRisk of writing below 75 if you are not genuinely fluent in that language
Ignoring Paper B entirely if writing GS in EnglishPaper B tests précis and translation skills not routinely practiced

Mentor Tips

  • Prepare for Paper A with at least 20–30 practice sessions on précis writing and translation. These are skill-based, not knowledge-based — you improve with drills.
  • For translation sections: Practise translating 1–2 paragraphs of editorial-level English text into your chosen Indian language and back every week for three months before Mains.
  • For Paper B: Native Hindi-medium candidates sometimes underperform on the English précis and translation sections. Spend 15 minutes a day for two months reading editorials and summarising them in 80 words — this is the entire skill being tested.
  • Do not choose a language for Paper A that you cannot write fluidly. Some candidates choose Sanskrit hoping it is easier — it is not, and poor Sanskrit results in disqualification.
