- Understand the Weightage: Since Sections I and II carry 400 out of the total 480 marks, allocate the majority of your study time to mastering core engineering concepts.
- Focus on Accuracy over Volume: With a negative marking of -1 for every wrong answer, avoid blind guessing. It is better to attempt fewer questions accurately than to risk losing marks through careless errors.
- Brush Up on B.Tech Basics: The engineering questions are designed at the graduate level. Review your university textbooks, especially for foundational technical topics like Electromagnetic Theory, Digital Electronic Circuits, and Control Systems.
- Do Not Ignore General Ability: Section III carries 80 marks and often acts as the deciding factor in the final merit list. Read daily newspapers for current events and familiarize yourself with basic Indian History, Geography, and current Telecom industry trends.
- Practice CBT Mock Tests: Time management is crucial for analyzing and solving 120 complex technical questions within a strict 3-hour window. Practice full-length online mock exams to improve your speed and adapt to the digital testing interface.
