GATE Application Date:28 Aug' 25 - 28 Sep' 25
The GATE 2026 exam for Computer Science Engineering (CSE), to be conducted by IIT Guwahati in February 2026, will assess candidates on a wide range of topics — from core theoretical foundations to applied problem-solving skills. To maximize scores, aspirants should focus on “hit and score” topics, which not only carry high weightage but are also areas where students commonly face challenges. Strengthening these sections can significantly improve accuracy and boost overall performance. A targeted preparation strategy aimed at such topics allows students to secure higher marks with efficient effort.

Some of the most scoring topics in the GATE 2026 CSE syllabus include Data Structures & Algorithms, Theory of Computation, Computer Networks, Operating Systems, and Databases — each consistently contributing substantial marks in past exams. Alongside these, Engineering Mathematics and Digital Logic often serve as high-yield areas where a strong conceptual base can lead to quick, accurate problem-solving. By prioritizing these key sections and practicing application-based questions, candidates can enhance both their speed and precision, increasing their chances of achieving a top rank in GATE 2026.
Here you can check and refer to topic wise weightage of CSE as per last few years. It will help you understand which topic holds the most value and how to prioritize topics. Check it below:

Databases | RDBMS, Normalization (1NF–BCNF), SQL Queries, Transactions (ACID), Indexing | ~4.72% weightage; direct application of concepts makes it quick to score in exams. |
Compiler Design | Lexical Analysis, Parsing (LL, LR), Syntax & Semantic Analysis, Code Optimization | ~4.49% weightage; moderate complexity but predictable question patterns. |
1. Prioritize High-Weightage and Scoring Subjects First
Prioritise high-weight courses like theory of computation, operating systems, computer networks, aptitude, engineering mathematics, data structures and algorithms, and so on. These sections can be mastered for fast scoring and frequently have predictable question patterns. Before going on to moderately weighted topics, identify reoccurring question types in previous years' papers and establish a completion goal for each subject.
2. Establish Firm Foundations Before Taking on Complex Issues
Instead of testing memorisation, GATE questions frequently assess conceptual clarity. Make sure you fully comprehend the theory, definitions, and fundamental examples in each subject before diving into complex numericals. For instance, understand pipelining before attempting numerical throughput calculations in Computer Organisation. This method guarantees that you can logically infer the answer even if the question is posed in a different format.
3. Practice with Topic-Wise and Full-Length Mock Tests
To ensure retention, immediately reinforce a subject by completing topic-specific tests after finishing it. As the exam approaches, take full-length timed mocks to simulate real exam conditions. Examine your performance in detail, determine whether any errors resulted from conceptual lapses, computation errors, or poor time management, and address them before the next mock. Frequent testing also enhances accuracy and speed under duress.
4. Keep your revision notes brief and to the point.
Revision can quickly become too much to handle with a syllabus as extensive as GATE CSE. Keep a single, succinct sheet for each subject that includes formulas, shortcuts, crucial definitions, and challenging ideas. When feasible, make use of flowcharts, diagrams, and mnemonics. For quick revision in the last month, use these condensed notes and previous exam questions rather than reading entire textbooks.
5. Use Wise Question Selection to Balance Accuracy
Accuracy is just as crucial in GATE as speed because of negative marking. Don't spend too much time on a single difficult problem; if it appears to take a lot of time, mark it for review and move on. To boost confidence, begin the paper with the most straightforward and well-known questions. Verify numerical responses and unit conversions twice at all times because even minor errors can result in a mark deduction. Sometimes a well-thought-out approach can have a greater impact than simple knowledge.
1. Focus on Topic Coverage and Test Patterns
Instead of jumping to preparation, focus on the last 10-12 years of GATE CSE papers. Start with the most recent papers as they carry more weight. Look for patterns of weightage such as the importance of Computer Networks, Operating Systems, and Engineering Mathematics. Always look for repeating patterns, for instance, most Aptitude questions can be classified into clusters as can questions of Compiler Design and its focus on lexical and syntax analysis. With such analysis, you will be able to tailor focus and track the areas that are most likely to be in 2026.
2. Blend Concepts and Core Problem Solving
While preparing for GATE, refrain from learning theory and problem-solving in blocks. Theory segment is best done on the go. For instance, after learning TCP congestion control, try to attempt questions on the same. The same applies to AVL tree rotations. Application with comprehension fortifies recall in the long run. In addition, constant recall in attempts reduces likelihood of concepts sliding away by the time the exam arrives.
3.Time management through sectional practice
To improve your speed and efficiency, practice solving specific classes within a short time frame. For example, give yourself 15-20 minutes for qualification, 25-30 minutes for engineering mathematics and 35-40 minutes for a main theme during practice sessions. This ensures that you are ready for the actual gate landscape, where the strategic allocation of time in the classes is important to try maximum questions without running at the end.
4. Use active recall and space repetition for memory retention
For a huge course in the form of GATE CSE, it is not enough to read just notes. Use active recall - Try to explain the concepts without looking at your notes or answering questions from memory. After resuming the same subject several times at the growing interval (eg, 1 day, 1 week, 1 month), start the same subject again and mix it with repetition. This technique is highly effective for remembering formulas, algorithms and theory-loving subjects such as theory of theory.
5. Elects the environment of the exam regularly
At least once a week, take a full-length gate mock test under conditions like strict examination, 3 hours, no break. It not only creates stamina for real examination, but also helps you to refine your question selection strategy. After each test, spend as much time in analyzing mistakes as you were writing the test. Identify whether errors were due to lack of knowledge, mistakes of calculation, misinterpretation of question, or bad time allocation - then adjust your strategy accordingly.

Yes, it will be acceptable. In GATE registration, the name should match your valid photo ID proof in terms of spelling, not the order. Many Indian IDs have surname written first, while the portal generates it as first–middle–last. Since all three parts of your name (Vikash, Rameshbhai, Bhagel) are correct, there won’t be any issue. Just ensure you upload the correct ID proof. During verification, they check spelling, photo, and signature, not the word order.
Hello,
Yes, you can change your category from General to OBC during the GATE 2026 correction window.
GATE always allows candidates to correct details like category. You will need to pay a small correction fee for this change. Make sure you upload a valid OBC certificate as per the format and date mentioned by GATE.
So, wait for the correction window, log in to your application, and update your category to OBC.
Hope it helps !
