Everything that decides whether you can sit for the Civil Services Examination: age limits by category, number of attempts, educational qualification, nationality rules — and the attempt-counting rule most aspirants get wrong.
You must be at least 21 years old on 1 August of the exam year. Upper limits and attempts vary by category:
| Category | Upper Age Limit | Attempts |
|---|---|---|
| General | 32 years | 6 |
| EWS | 32 years | 6 |
| OBC | 35 years (+3) | 9 |
| SC / ST | 37 years (+5) | Unlimited (till age limit) |
| PwBD (Gen/EWS) | 42 years (+10) | 9 |
| PwBD (OBC) | 45 years | 9 |
| PwBD (SC/ST) | 47 years | Unlimited (till age limit) |
Additional relaxations exist for ex-servicemen, defence services personnel disabled in operations, and certain domiciles — refer to the official notification for the full list.
An attempt is counted the moment you appear in any one paper of Prelims. Applying but not appearing costs nothing. This is why a serious, mock-tested attempt matters — never walk into Prelims unprepared just to “see the paper.” You can see real papers anytime in our PYQ bank and simulate the exam with a full-length mock.

A General category candidate must be at least 21 and not more than 32 years of age as on 1 August of the exam year. For CSE 2027 that means as on 1 August 2027. EWS candidates have the same age limit as General (no relaxation).
General and EWS candidates get 6 attempts. OBC candidates get 9 attempts. SC/ST candidates have unlimited attempts up to their age limit of 37 years. PwBD candidates of General/EWS/OBC categories get 9 attempts.
An attempt is counted only when you actually appear in at least one paper of the Preliminary Examination. Merely applying for the exam and not appearing does not count as an attempt.
Yes. Candidates appearing in the final year of their qualifying degree (or awaiting results) can apply for Prelims provisionally. They must produce proof of passing the degree with the Mains application (Detailed Application Form).
No. UPSC requires only a bachelor’s degree from a recognised university (including distance/open universities recognised by UGC). There is no minimum marks requirement in graduation.
Persons with Benchmark Disability get up to 10 years of upper-age relaxation — a PwBD candidate of the General category can appear up to 42 years of age. PwBD relaxation stacks with the category relaxation rules as detailed in the official notification.
For the IAS, IFS and IPS, a candidate must be a citizen of India. For certain other services, subjects of Nepal/Bhutan, Tibetan refugees who came before 1 January 1962, and persons of Indian origin who migrated from specified countries with intention of permanent settlement are eligible, subject to a certificate of eligibility from the Government of India. Check the official notification for exact provisions.
Yes. Appearing in any one paper of the Prelims counts as one full attempt of the CSE, regardless of whether you qualify for Mains. Disqualification or cancellation of candidature also counts as an attempt.
With limited attempts, preparation quality decides everything. Train with Sherlocking-powered mocks before you burn an attempt.
