“I solved all 5 predicted Math papers from KnowZoid in the last week before boards. 7 out of 10 questions in my actual paper were from them. Scored 96.”
Aanya Sharma
CBSE · Class 10 · DPS RK Puram
“Trigonometry was my worst topic. Their top-10 repeated questions covered almost everything that came in my board exam. 3 marks saved, easily.”
Dev Kumar
ICSE · Class 10 · St. Columba's
“₹199 for 5 papers is basically free. The accuracy report convinced my mom we should try it. Worth every rupee — got 94% in Science.”
Ishita Bhat
UP Board · Class 10 · Kanpur
“Not every predicted question will come, they're upfront about that. But the weakness-targeted papers in Pro tier are genuinely useful.”
Kabir Menon
CBSE · Class 12 · Delhi Public School
“The chapter-wise weightage chart alone is worth the signup. Showed me I was spending too much time on Probability — which is only 5% of the paper.”
Zara Khan
Maharashtra Board · Class 10 · Pune
“My tuition teacher laughed when I told him about this app. After my prelims result, he asked me to send him the link.”
Vihaan Rao
