Prelims OR Mains – Which Stage (Topics) Should You Prepare First for UPSC Civil Services Exam?

1. India Since Independence (GS Paper 1).
2. World History (GS Paper 1)
3. Indian Society (GS Paper 1)
4. Foreign Relations (GS Paper 2)
5. International Affairs (GS Paper 2)
6. Internal Security (GS Paper 3)
7. Disaster Management (GS Paper 3)
8. Ethics, Integrity and Aptitude (Entire GS Paper 4)
9. Essay Paper (There is no essay in Prelims!)

Is 3 months after UPSC Prelims enough to cover Optional Subject, Current Affairs, and Additional GS Topics for UPSC Mains?

That’s a big question!

Usually, UPSC conducts the Preliminary Exam in June, followed by the Main Exam in September.

The time gap between Prelims and Mains would be hardly 3 months (approximately 100 days).

Unless you are extremely brilliant and hardworking, it is not easy to satisfactorily cover the Optional Subject, Ethics Paper, Additional GS Topics, and Current Affairs in 3 months – if you are a first-timer.

We are not saying that it is impossible. It is certainly possible, and many toppers have already done that. However, it’s not an easy task for any first-timer.

What if you start preparing for Prelims First?

For most aspirants, it’s quite natural to start from Prelims topics – as the Preliminary Exam is the first stage. It’s not a bad strategy. After all, you cannot write the Main exam if you don’t qualify Prelims.

Both papers of Prelims has to be given its due importance. However, your Prelims preparation should not compromise Mains.

You should ensure that you have enough time to cover the Mains topics as well. It might take considerable time to cover your optional subject. Besides, not everyone would not have exam-oriented writing skills. And, to develop writing skills, it requires time and effort.

What if you start preparing for Mains First?

There are many candidates who follow the reverse approach of preparing for Mains first, followed by Prelims. Well, this can be a quite useful strategy for many. Those already follow this method, we appreciate your pre-planning and long-term vision 🙂

However, don’t get too immersed in Mains that you forget the requirements of Prelims (solving MCQs with good accuracy, within a time limit).

If you start preparing for Mains first, you should finish most of the Mains topics (including optional subject), much before Prelims. At least 6 months should be given for dedicated Prelims preparation – if you are appearing for Prelims for the first time. Only Current Affairs topics should remain for Mains- which you can easily cover in the 3-4 month period between Prelims and Mains.

If you have only less than 6 months for Prelims, focus more on the topics related to UPSC Prelims.

However, if you are an early starter, who has 10-12 months time for advance preparation, devote time to cover the topics mentioned only in the UPSC Mains syllabus like Ethics, Optional etc along with your Prelims preparation.

Whatever be the case, see the big picture.

Take your Prelims and Mains preparation together whenever possible.
