UPSC Prelims Exam-Day Strategy: Why Your Old Approach Won’t Work Anymore!
Until 2018, solving the Prelims was straightforward - you could confidently attempt 35-40 questions in Round 1 and keep another 40-45 for review. The 120 minutes felt enough.
But post-2019, the game changed.
Now, you struggle to solve even 25-30 questions in the first round. The ones you mark for review? They’re tougher, trickier, and nearly impossible to eliminate confidently. The result? More guesswork, more mistakes, and a lower score.
The old strategy no longer works.
The difficulty level has increased, and most aspirants are failing not because they don’t know enough, but because they don’t have the right exam-day approach.
So, what should you do?

Sarrthi IAS is the one-stop solution for UPSC CSE Preparation focusing on three main pillars…
Everyone dreams of cracking UPSC. But few talk about the real challenge - not the syllabus, not the vast books, but habit-building.
Success in UPSC is not just about intelligence; it’s about consistency. The ability to sit down, study every day, & stay away from distractions. That’s why those from IITs, NITs find it easier. They’ve built the discipline over years.
For most aspirants the struggle is different. They start with enthusiasm, but without the right habits, the momentum fades. That’s where the real battle is lost.
If you're still in college & don't know how to build a study pattern that sticks, start now. The sooner you train yourself to follow a structured schedule, the better your chances of making it to the final list.
This is exactly why we designed the GS Foundation Course - not just to teach, but to instill the discipline required for UPSC success.
Start building the right habits today.

Transcription Factors & Gene Regulation | Explained
Transcription Factors are proteins that bind to DNA and control gene expression. They play a crucial role in cell differentiation, identity, and response to the environment.
This is not an easy concept to grasp, yet it's an essential topic - especially since it's part of the NCERT. In the Science & Tech Course, Shivin Sir breaks it down in-depth, making it easier to understand.
These concepts can’t be memorized in isolation - a strong foundation is key to truly understanding them.
Now, if UPSC asks a question on this topic, you'll already have a solid understanding of the various levels of gene regulation - helping you tackle it with confidence! ✅

"The Mindset That Cracks UPSC"
Fixed Mindset: “I’m not good at this.” 🚫
Growth Mindset: “I can’t do this… yet.” ✅
UPSC isn’t about how smart you are today - it’s about how willing you are to grow.
Struggle with PYQs? → Practice daily.
Can’t recall concepts? → Revise smartly.
Weak in answer writing? → Improve step by step.
Every topper once struggled. The difference? They didn’t give up.
2026 is yours - if you start with the right mindset.

We all have biases while attempting a UPSC test, even if we don’t realize it!
These biases also affect our performance in the actual UPSC Prelims Exam.
When answering a question, we act on two types of biases:
✅ Positive Bias – Based on facts and knowledge.
❌ Negative Bias – A feeling that “something seems wrong” even without certainty.
If you analyze your tests, you may find that Negative Bias often overpowers Positive Bias, leading to poor results.
So, how do you eliminate these biases?
Watch Varun Sir explain how to overcome them and boost your UPSC Prelims Score!

The Mindset That Makes a UPSC Topper
You say, “UPSC is tough.” True.
You say, “The syllabus is vast.” Yes.
You say, “Only a few get selected.” That’s a fact.
But the real question is – do you have a fixed mindset or a growth mindset?
❌ Fixed Mindset: "I’m bad at answer writing, I’ll never improve."
✅ Growth Mindset: "If I practice daily, my writing will get better."
Every topper struggled at some point. The difference? They believed in the power of yet.
🚀 You can’t solve PYQs yet.
📖 You don’t know the syllabus yet.
✍️ You don’t write great answers yet.
But if you start today - with consistency, patience, and the right mindset - you won’t just prepare for UPSC 2026. You’ll transform into the kind of person who cracks it.
