You've been practicing in the dark.
Coaching gave you content. Nobody gave you correction.
UPSC Mains is a writing exam. The gap between 850 and 950 isn't knowledge — it's knowing exactly which 3 things to fix in each answer. Traditional coaching checks off syllabus. Nobody sits with your specific answers and tells you why they fall short.
Less than 1% of coaching cost. Infinitely more specific.
Coaching institutes charge ₹1–2 lakh for generic evaluation. We charge less for feedback that actually names your gaps.
