Manual grading
200 students × 5 problems = 1,000 submissions to grade by hand every week. Faculty burn out. Results take days. Students lose interest.
| Roll No | Q1 | Q2 | Q3 | Status |
|---|---|---|---|---|
| CS-001 | 8 | 10 | — | Pending |
| CS-002 | 10 | — | — | Pending |
| CS-003 | — | — | — | Not started |
| CS-004 | 7 | 9 | 6 | Graded |
| CS-005 | 9 | 10 | — | Pending |
Rampant copying
No way to detect plagiarism. Students share solutions freely across WhatsApp groups. You can't tell who actually solved it.
for(int i=0; i<n; i++) { int comp = target - nums[i]; if(mp.count(comp)) return {mp[comp], i}; mp[nums[i]] = i; }
for(int i=0; i<n; i++) { int comp = target - nums[i]; if(mp.count(comp)) return {mp[comp], i}; mp[nums[i]] = i; }
No proctoring
Students freely switch between ChatGPT, WhatsApp, and the exam window. You have no idea what's happening during the test.

WhatsAppZero visibility
You find out students are struggling at the end of semester. No dashboards, no analytics, no early warnings. Too late to help.
Sound familiar? There's a better way.
One platform.
Complete control.
Everything your coding lab needs.
Nothing it doesn't.
Submit. Blink.
Already graded.
Students submit. Verdicts appear in under 2 seconds — Accepted, Wrong Answer, TLE, the works. Test case breakdown, execution time, memory usage. Zero manual work.
Built before your
chai gets cold.
Tell the AI the topic and difficulty. It writes the problem statement, generates test cases, validates against a reference solution. You review and publish.
Hints, not answers.
24/7.
Students get stuck — the AI nudges them with Socratic hints, not solutions. It reads their code, understands the problem, and asks the right questions. Like office hours that scale to 500 students at once.
Real competitive programming.
In your college.
ICPC penalty scoring or IOI partial credit — your pick. Live leaderboard with freeze. Access codes for private contests. Late join support. Your students practice the same format top companies use to hire.
It watches so
you don't have to.
The moment a student opens a proctored exam, monitoring starts silently. Tab switches? Logged. Dev tools? Caught. Copy-paste? Blocked. Every violation hits your admin panel instantly — real-time, not after the exam.
See every screen.
In real time.
Faculty can watch any student's screen live during a contest or exam. No extra software. No student setup. WebRTC-powered, built right into the platform.
Know who's struggling
before they fail.
Which students are falling behind. Which problems are too hard. Where your course needs adjustment. AI-powered insights that tell you what's happening — not just charts that show you what happened.
Their progress.
At a glance.
Every student gets a personal dashboard — problems solved, streaks, contest history, and performance trends. They see exactly where they stand and what to work on next.

No per-student fees. No USD pricing. No 6-month procurement cycle.
We used to spend 40+ hours grading per semester. CDeX made it fully automatic — our faculty now focuses on teaching, not paperwork.
The proctoring system caught 23 plagiarism cases in our first exam. Paid for itself on day one.
Students love the instant feedback. Submission rates went up 3x after we switched from email-based assignments.
Setting up took less than a day. We imported 600 students from a CSV and were running our first contest by afternoon.
The contest mode with live leaderboards has completely changed how students engage with coding. They actually compete now.
We tried HackerRank but per-student pricing was insane. CDeX gives us the same features at a fraction of the cost.
