Learn Computer Science From a Former BARC Scientist
Hi, I'm Nilesh Nama. During my preparation journey, I secured **BARC AIR 12** and **GATE CS AIR 202**. I designed these cohorts with a singular focus: training you to think from first principles. We don't teach shortcuts; we build system-level intuition so you can tackle complex questions.

Rohan Khamitkar
AIR 44
IIT Bombay
The mock interview practice and deep compiler design insights allowed me to excel. If you want raw depth in CS concepts instead of superficial formula tricks, this is the only prep program you should join.
Harsh Raja
AI, IISc Bangalore
Securing a top rank was about how to think under pressure. The database transactions and query tuning framework helped me clear complex multi-layered questions in minutes. Nilesh's focus on structured problem-solving was the key game changer.
Jay Bansal
AIR 9
IIT Bombay
Intuitively understanding the OS concepts rather than rote formulas saved me in the exam. Under Nilesh's guidance, I stopped memorizing scheduling and paging math, and started reasoning through the hardware constraints. The best program for core CS.
