Pinaka · Assessment infrastructure for coaching centres
The diagnostic depth of the top 10.
For every coaching centre.
Know exactly why every student lost marks. Topic mastery, stamina, pressure, decision patterns. All under your brand. Per-exam pricing. No infrastructure team required.
Every coaching centre publishes a rank list.
Few can explain why a student lost 60 marks.
That gap is not about effort. It is about infrastructure. The top chains have in-house tech teams and proprietary analytics. Everyone else has spreadsheets and instinct.
We built Pinaka to close that gap.
The real difference
What you say when a parent asks
"How is my child doing?"
Without Pinaka
"Your son scored 420 out of 720. Rank 340. He needs to study harder."
Same conversation every parent gets. No insight. No plan. No reason to stay.
With Pinaka
"Your son lost 60 marks, but 35 were careless mistakes, not gaps in knowledge. His Organic Chemistry looks strong on easy questions but breaks down on hard ones. He knows the basics but hasn't built depth yet. His accuracy drops 28% in the last hour. We're starting endurance drills this week."
Specific. Actionable. The kind of answer that makes parents tell other parents.
Every coaching centre says they care about student outcomes.
Pinaka gives you the data to prove it.
What one exam reveals
Every wrong answer, classified.
Pinaka tells you why each student lost marks. And what they need to do differently. Not a rank list. A diagnosis.
This is what you tell parents after every mock test.
Score
450 / 720
Rank
340 / 3,500
Error Classification
Conceptual gap
42% of the class made the same mistake
Careless rush
Answered in under 15 seconds. Needed 60.
Bad revision
Changed answer from correct to incorrect
Sample output from Pinaka's scoring engine.
Beyond the score
Five dimensions of how a student takes an exam.
Topic Diagnosis
Easy questions right but hard ones wrong? That's Surface Knowledge. Not mastery. Per topic, per subtopic.
Exam Stamina
| Time period | Accuracy |
|---|---|
| 0–45 min | ~78% |
| 45–90 min | ~72% |
| 90–135 min | ~64% |
| 135–180 min (crunch) | ~50% |
Accuracy drops 28% in the last 45 minutes. Now you know if they need endurance strategy, not more content.
Pressure & Decisions
PRESSURE PERSONA
Fading Focus
Performance degrades despite steady pacing
ANSWER CHANGES
Changes hurt by 15 marks
First instinct was right 80% of the time
TIME BUDGET
12 minutes wasted
Stuck on 3 questions they got wrong
So you know which students need strategy coaching, not more content.
Across exams
Track progress per topic across every mock test.
Know if the coaching is working. Before the real exam.
12 metrics per student
Across exams
Every mock test makes the next one smarter.
Pinaka tracks each student across exams. Not just their scores, but how their patterns change. Which topics are improving and whether stamina is building. How they handle pressure differently each time.
After three mock tests, you'll know exactly which students are improving, which are
plateauing, and which need intervention.
Before the real exam.

Built for scale
2,50,000
students taking an exam at the same time. Every one of them gets their result.
100K
students scored in under 3 minutes. Because a student waiting a week for diagnostics has already moved on.
99.99%
uptime, by architecture. A crashed exam is not a server metric. It is a student's year lost.
Works on 3G
Built for the bandwidth reality of Tier 2 and Tier 3 India. Not just the metros.
The infrastructure should have existed. We built it.
Exam integrity
10 behavioral signals.
One risk score.
Every exam is proctored. Pinaka tracks tab switches, device changes, copy-paste attempts, and more. Each student gets a risk score that lets you flag issues without guessing.
Monitored signals
No camera required. No software install. Browser-native.
So honest students aren't competing against those who aren't.
Why we built it this way
Diagnostic intelligence shouldn't be a luxury.
The largest coaching chains have custom platforms and proprietary analytics. Their students get 5-dimension diagnostic profiles. Everyone else's students get a rank list and a percentage.
A 500-student institute in Tier 2 should have the same diagnostic power as the largest chain in Kota. We built Pinaka for that. Not because we are competing on price. Because this infrastructure should have existed.
