Hi

hope you doing well

To crack PSU exams from the Computer Science department, especially if you’re starting your preparation in the second year of B.Tech, you can follow a structured approach:

Know the PSUs : Different PSUs (like BHEL, ONGC, IOCL, etc.) may have specific preferences in terms of syllabus and exam patterns. Familiarize yourself with the GATE exam structure since many PSUs recruit through it.

Concentrate on core Computer Science subjects, including:

• Data Structures and Algorithms
• Operating Systems
• Databases
• Computer Networks
• Software Engineering
• Theory of Computation
• Additionally, some PSUs may focus on general aptitude and engineering mathematics.
  

Strengthen Basics : Use your second year to solidify your understanding of fundamental concepts. Consider enrolling in extra courses or online platforms to cover any weak areas.

Recommended Books : Refer to standard textbooks for each subject. Books like “Introduction to Algorithms” by Cormen, “Operating System Concepts” by Silberschatz, and “Computer Networking” by Tanenbaum are good starting points.

Regularly take mock tests to familiarize yourself with the exam format and improve time management skills.

Hope you get it and find it useful

All the best for your Preparation.
