Why 3D learning works

Concepts you can see, touch and replay

Competitive exams reward understanding, not rote learning. Every topic in 369 Tesla is an interactive laboratory you control.

Interactive 3D simulations

Rotate, zoom and step through CPUs, memory, trees, graphs and network stacks instead of staring at static diagrams.

Unit-wise, syllabus-mapped

Labs follow the TN TRB Computer Instructor units and all ten UGC NET CS Paper 2 units, so you always know what to study next.

Progress that follows you

Continue exactly where you stopped on any device. Completed labs and active learning time are tracked for you.

Tamil-friendly explanations

Key ideas explained in Tamil so Tamil-medium graduates learn with full clarity — தமிழிலும் புரியும்படி.

Learn anytime, no installs

Everything runs in your browser on a laptop, tablet or phone. Replay a difficult concept as many times as you need.

Private, secure access

Your personal login unlocks exactly the courses you enrolled in. Safe, ad-free and distraction-free.

CPU PipelineCycle 1

Five instructions flow through the IF → ID → EX → MEM → WB stages. After the pipeline fills, one instruction completes every clock cycle.

FAQ

Frequently asked questions

What is 369 Tesla?

369 Tesla is an online learning portal by Kalviyogi (Edunivra Private Limited) that teaches computer science through interactive 3D simulations. It is designed for Tamil Nadu TRB Computer Instructor (Grade I) and UGC NET Computer Science aspirants.

Which exams does it help with?

The labs follow the units of the TN TRB Computer Instructor Grade I syllabus and the ten units of UGC NET Computer Science and Applications Paper 2. They are also useful for PG TRB, polytechnic TRB, SET and university computer science courses.

Do I need to install any software?

No. Every lab runs in a modern web browser on a computer, tablet or phone. You only need your login details.

Is the content available in Tamil?

The portal interface and labs are in English, with Tamil explanations for key concepts so that Tamil-medium learners can follow comfortably.

How do I get access?

Accounts are created by the Kalviyogi team. After enrolment you receive a username and password, and the courses assigned to you appear on your dashboard immediately.

How is this different from video classes?

Video classes show a concept once. In a 3D lab you operate the concept yourself — step a CPU pipeline, insert into a B-tree, route a packet — as many times as you need, and your progress is saved.

Can I track my progress?

Yes. The portal records which labs you opened, the time you spent and what you completed, so you can continue exactly where you left off.
