There is no single best stream that guarantees success to crack the IAS examination, one of the toughest entrance exams in India. However, a Humanities background is considered to be the most advantageous.
Even so, there have been IAS toppers with varying backgrounds. In this article, I am going to be informing you of how your stream selection after Class 10th matters, which subjects to take in Class 11th and 12th, and more.
Let us start!
Why Your Stream Choice Matters
The Union Public Service Commission (UPSC) examination is one of the highly competitive ones in India. It has three parts: Prelims, Mains, and the Interview.

Any candidate from Science, Commerce, or Arts/Humanities is eligible for the examination. However, your choice of stream as well as subjects within the stream can significantly impact your preparation and readiness for the exam.
The UPSC syllabus consists of a large number of questions from the category, “General Studies” or GS, which covers a wide range of subjects.
This makes it very important to go for the right stream. It helps you get ahead and prepares you conceptually as well.
Which Subjects Are Best For IAS In Class 11 and 12?
Ideally, it is recommended to select subjects that match the UPSC syllabus. Below are some high-value subjects to consider:
- Political Science
- History
- Geography
- Economics
- Psychology
- Sociology
- Public Administration
- Philosophy
These are the main topics for the General Studies exams. These carry the most weight in both the preliminary and main stages of the UPSC. But keep in mind that the full list of subjects is much longer and can change depending on the school or board you attended.
Which Degree Is Best To Become An IAS Officer?
The most common degrees pursued by successful candidates are a Bachelor of Arts (B.A.), Bachelor of Science (B.Sc.), Bachelor of Commerce (B.Com.), and Bachelor of Technology (B.Tech.). However, a degree in BA is often considered to be the best choice.
A Bachelor of Arts degree has subjects from the humanities and social sciences and directly overlaps with a large portion of the UPSC CSE syllabus. This way, you can prepare for the exam while doing your degree.
But it’s important to remember that a single stream or degree does not guarantee success. There have been many IAS toppers from engineering and medical backgrounds.
How To Prepare For IAS Alongside School Studies
One of the best tips to prepare for the IAS exam is to start studying early. Here are some strategies to help you crack your dream exam:
1. Read NCERTs (Class 6-12)
The first thing to do is to read NCERT books for classes 6 to 12, no matter what your stream is. These books contain a clear explanation of important concepts in concise language. They are most important for subjects like History, Geography, and Political Science.
2. Develop Current Affairs Awareness
Developing current affairs awareness by reading newspapers goes a long way. When you wake up in the morning, simply pick up The Hindu or The Indian Express Daily and go through it while sipping on your coffee.
3. Build Analytical and Writing Skills
Pick up any topic of your choice and practice writing essays and long answers. This is one of the most important skills you’ll require for your Mains exam to write well-structured answers.
Tips For Students From Non-Humanities Backgrounds
If you have already opted for a non-Humanities stream or degree, don’t worry; you can still crack the IAS examination.
People with Science or Commerce backgrounds have a unique advantage. They have greater logical reasoning and analytical skills, perfect for the CSAT (Civil Services Aptitude Test) paper. This paper tests your comprehension, reasoning, and basic numeracy skills.
On the other hand, to cover the humanities-based topics, you can follow these tips:
- Start with clearing your basics by going through the NCERT books thoroughly.
- Identify subjects in your degree/stream that overlap with the UPSC syllabus.
- Practice writing long answers if your stream does not emphasize descriptive writing.
Remember that it’s all about how you make the most with what you have and doing strategic study, rather than letting your stream choice define your potential for success.
Expert Recommendations: What IAS Toppers Say About Stream Selection
According to numerous IAS toppers, the stream you choose is not a barrier to success. Here are some insights from successful toppers:
- Ishita Kishore (AIR 1, 2022), a commerce graduate, made notes herself and practiced writing answers to secure the top rank. She advises, “Understanding the crux of the subject matter is key.” (Source)
- Aditya Srivastava (AIR 1, 2023) is an IIT Kanpur alumnus. He says that strategy played a larger role than pure hard work. He states that analyzing previous years’ papers and using technology like Google and ChatGPT were “helpful” in identifying question patterns. (Source)
- Anu Kumari (AIR 2, 2017) has a background in Physics and Finance and points to the importance of self-analysis. She says, “I used to analyse where my demotivation is coming from, and I worked on that.” (Source)
There are toppers from diverse streams, which tells us that anyone is capable of cracking the exam.
There Is No Single “Best” Stream For IAS
Ultimately, it is not possible to define a “best” stream for the IAS exam. What determines whether a student will succeed will, instead, come down to personal work ethic and personal interest.
While pursuing a background in Humanities can give a student the most advantage with regard to the syllabus, a Science or Commerce background will also provide equally valuable analytical skills to help succeed.

Humanities often gives aspirants a natural advantage with subjects like History, Geography, and Political Science overlapping directly with the UPSC syllabus. However, students from the Science and Commerce streams also have analytical and logical reasoning ability.
