How to prepare for the IAS Mains?

Question

I am looking for a practical answer to this UPSC question: How to prepare for the IAS Mains?

If someone has prepared seriously for this part of the UPSC process, please share a clear strategy, useful resources, and the mistakes that usually waste time. Honest advice from repeat aspirants would help a lot.

Gaurav Kannan · Answer

Preparation changes a lot depending on whether you mean prelims, mains, or CSAT. Treating them the same is one reason many plans feel messy.

That is usually where preparation starts feeling more manageable.

Sanjana Malhotra · Answer

The easiest way to think about it is:
- prelims needs accuracy and elimination
- mains needs structure and depth
- CSAT needs timed practice and calm execution
The study style has to match the output.

That small shift alone can save a lot of time.

Deepika Pant · Answer

Students often keep reading new content when the stage actually demands practice under pressure. That is where marks get lost.

Most people improve once that part becomes clear.

Rhea Roy · Answer

Once the basics are decent, mock analysis becomes more valuable than endlessly adding fresh material.

Aryan Sridhar · Answer

The revision pattern also changes by stage. Prelims needs compression, mains needs layered understanding.

This is why simpler plans often work better for longer.
