The role of the core subject in GATE
For most engineering papers the core subject carries about 72 of the 100 marks, as published for GATE 2026, which makes it the largest determinant of your score. The questions are conceptual and numerical, mix MCQ, MSQ and NAT types and are at the level of an undergraduate course with a focus on application. The syllabus is specific to your paper code, so the pages on TestMint cannot list it for every discipline; use the official brochure for yours. What can be said generally is how to prepare it, how to test it and how to read your results.
How the core questions behave
| Style | What it asks | Preparation |
|---|---|---|
| Concept recall and understanding | Definitions, properties, short reasoning | Concise notes; spaced revision |
| Numerical problems | Compute a quantity from given data | Worked problems; unit discipline |
| Multi-step application | Combine two or three ideas | Topic-mixing sets |
| Statement-based (MSQ) | Judge each statement or option | Understand exceptions and conditions |
A topic-wise method
- List the topics from the brochure and note their approximate weight from recent papers.
- Study a topic, solve problems and take a 10 to 15 question test.
- Record accuracy by topic in a table.
- Rank topics by marks at stake: weight multiplied by the gap in your accuracy.
- Revise the top of the list first, then retest.
An illustration with invented topics and accuracies:
| Topic | Approx. marks in a paper | Your accuracy | Marks at stake |
|---|---|---|---|
| Topic A | 10 | 50% | 5.0 |
| Topic B | 8 | 80% | 1.6 |
| Topic C | 12 | 60% | 4.8 |
| Topic D | 5 | 40% | 3.0 |
Marks at stake is weight × (1 − accuracy). Topic A (5.0) and Topic C (4.8) are the first priorities, even though Topic D has the lowest accuracy, because the weights differ. The weights here are made up for the example; take yours from the previous papers of your discipline.
Handling MCQ, MSQ and NAT in the core
- MCQ: eliminate by dimension, limiting cases and sign checks before computing.
- MSQ: evaluate each option separately; no partial credit as published, so be sure of each.
- NAT: compute carefully, check units and the permitted range of rounding.
Detailed rules are in the GATE pattern guide.
Time management
The core takes the bulk of the 180 minutes. A plan:
| Stage | Time (about 120 minutes) | What to do |
|---|---|---|
| First pass | About 70 minutes | Answer the questions where the method is clear |
| Second pass | About 40 minutes | Two-mark questions; NATs; eliminate on MCQs |
| Check | About 10 minutes | Recheck NATs and MSQ options |
Do not let a single two-mark question run beyond four or five minutes on the first pass.
Negative marking in the core
MCQs lose one-third of the question's marks when wrong, so a two-mark question costs two-thirds. Attempt MCQs when you can eliminate at least two options. NAT and MSQ carry no negative marking as published, so the decision is whether you have a method. See our negative marking guide.
How to practise
- Topic tests: after each topic, with a revisit a few weeks later.
- Previous-year questions: by topic, after studying.
- Full papers: weekly in the last six to eight weeks.
- Error log: by topic. See how to build an error log.
Analysing your result
| Pattern | Probable cause | Action |
|---|---|---|
| Errors concentrated in a topic | Concept gap | Re-study; retest |
| Errors in MSQ | Missing a condition or exception | Check each option separately |
| NAT errors | Arithmetic, units or rounding | Check units; use the calculator carefully |
| Many unattempted | Slow methods | Shortcuts; cap per question |
| Accuracy falls late | Stamina | Full three-hour papers |
Common mistakes
- Studying everything evenly without ranking topics by marks at stake.
- Reading theory without solving problems.
- Skipping previous-year questions or using them without studying first.
- Not practising MSQs, which need careful reading of each option.
- Using materials for a different paper code.
