Important areas included:
- C
- C++
- Operators
- Expressions
- Constructors
- Programming language concepts
For example, the response record contains C-programming questions in the Computer Science section. UGC_NET_June2026_PYQ
4. Matching-Type Questions
The paper included several questions requiring candidates to match concepts from two lists.
These questions can be time-consuming because candidates need to verify multiple relationships before selecting the correct option.
5. Comprehension-Based Questions
The paper also included question groups based on a common passage or problem.
A notable example is the CFG-based comprehension set toward the end of the Computer Science section, where multiple questions were based on the same grammar. UGC_NET_June2026_PYQ
This means students should also practice comprehension-based technical questions, not just independent MCQs.

A good preparation strategy should not simply be:
Read Theory → Give Mock Test
Instead, follow a cycle:
Step 1 – Complete the Concept
Understand the fundamental concept first.
Step 2 – Solve Topic-Wise Questions
Immediately solve PYQs related to that concept.
Step 3 – Identify Repeated Patterns
Maintain a list of:
- Frequently asked concepts
- Important formulas
- Common traps
- Repeated question patterns
Step 4 – Practice Numerical Questions
Give special attention to:
- Algorithms
- OS
- Networks
- Architecture
- Discrete Mathematics
- Probability
Step 5 – Practice Code Questions
For C/C++:
- Trace execution manually
- Check operator precedence
- Check type conversion
- Analyze pointers
- Analyze loops and recursion
Step 6 – Take Full-Length Tests
After completing the syllabus, move from topic-wise practice to complete mock tests.
