Role at ExamRig

Pankaj is responsible for the Computer Science learning material published on ExamRig. His review focuses on conceptual accuracy, understandable explanations, worked examples, revision value, and the types of comparisons and questions students commonly encounter while preparing for teaching and other competitive examinations.

Practical software-development experience is used to connect textbook concepts with real systems—for example, relating operating-system ideas to running applications, database concepts to application design, and networking principles to web communication.
