IAS Kaise Bane: Eligibility, Exam Stages and Preparation Plan

If you are asking IAS kaise bane, the short answer is this: you must clear the UPSC Civil Services Examination and then rank high enough to get the IAS cadre. The exam is held once a year in three stages. Therefore, first, learn the eligibility rules and the exam pattern. Then build a steady plan, because the exam rewards consistency over a long period.

IAS Kaise Bane: Eligibility

First, you need a bachelor’s degree from a recognised university. Final-year students can also apply, but they must produce proof of passing before the Mains application. Next, the age limit is 21 to 32 years for the general category. It goes up to 35 years for OBC candidates and up to 37 years for SC and ST candidates. Candidates with benchmark disabilities and some other groups get extra relaxation as per the official notice.

The number of attempts is also limited. The general category can take 6 attempts, while OBC candidates can take 9. For SC and ST candidates, there is no limit on attempts until the upper age limit. Note that an attempt counts when you appear for even one paper in Prelims.

The UPSC Exam Calendar for 2027

For CSE 2027, the notification is expected on 13 January 2027. Prelims is scheduled for 23 May 2027, and Mains is planned to start on 20 August 2027. These dates can change. Hence, confirm them on the official website before you plan.

Stage 1: Prelims

Prelims has two objective papers of 200 marks each. First, General Studies Paper I has 100 questions. Second, the CSAT paper (General Studies Paper II) has 80 questions and is only qualifying, with a minimum of 33 percent. Moreover, every wrong answer costs one-third of the marks for that question. As a result, careful guessing matters.

The cutoff is based on Paper I alone. Therefore, spend most of your Prelims time on current affairs, history, polity, geography, economy, environment and science.

Stage 2: Mains

Mains is a descriptive exam, and it has nine papers. Two of them are qualifying language papers (an Indian language and English), which carry 300 marks each. In contrast, the other seven count towards your rank. They are the Essay paper (250), four General Studies papers (250 each) and two papers of your optional subject (250 each). Together, these make 1,750 marks.

Your answer writing decides this stage. Hence, practise writing in a fixed time, and use diagrams, maps and examples where they help.

Stage 3: Interview

The Personality Test carries 275 marks. In it, a panel asks about your background, your opinions and current issues. It is not a test of facts alone. Instead, the panel looks at clarity, honesty and balance. Together, Mains and Interview make the final 2,025 marks, and your rank comes from this total.

Stage	Type	Marks	Counts in rank
Prelims	Objective, 2 papers	200 + 200	No (screening)
Mains	Descriptive, 9 papers	1,750	Yes
Interview	Personality test	275	Yes

Step-by-Step Preparation Plan

1. Read the syllabus first. Print it, and then tick topics as you finish them. For a full breakdown, see the UPSC syllabus guide.
2. Build the base with NCERT books. Begin with the middle and senior school books on history, geography, polity and economy.
3. Add a standard book per subject. Do not collect too many books, since revision then suffers.
4. Read a newspaper daily. Then make short notes on current affairs and link them to the syllabus.
5. Choose an optional subject. Pick one that interests you, has a clear syllabus and overlaps with General Studies.
6. Practise answer writing early. Start before Prelims, because Mains skills take time.
7. Take mock tests. Also, solve past papers and test series, and review each mistake.
8. Revise in cycles. Therefore, repeat each subject at least three times before the exam.

How Many Hours Should You Study?

Most successful candidates study six to eight focused hours a day for around a year. However, quality matters more than hours. Break the day into blocks: static subjects in the morning, current affairs in the afternoon and answer writing or revision in the evening. Also, take one day a week for revision and a mock test. Because the syllabus is large, a fixed timetable protects you from drifting.

Common Mistakes Aspirants Make

• Many start with too many sources, so they never finish one.
• Some ignore the CSAT paper, and then fail the 33 percent mark.
• Others skip answer writing until after Prelims, which leaves too little time.
• Finally, several copy a topper’s plan without checking whether it suits them.

After You Clear the Exam

The service you get depends on your rank and your choices. Top rankers are allotted the IAS. After that, selected officers train at the Lal Bahadur Shastri National Academy of Administration, and they start at Pay Level 10, with a basic pay of ₹56,100 a month plus allowances. Later, they serve as sub-divisional magistrates and district collectors, and move up to secretary-level posts.

Which Other Exams to Try Alongside

A backup helps many aspirants. For instance, the SSC CGL syllabus leads to central government jobs, and government jobs after 12th lists options for earlier stages. Also visit the Exam Prep category for more guides, and how to stop procrastinating if you struggle to stay consistent.
