Checked 25 September 2026. GATE 2027 eligibility is official and fixed. Programme admission rules are from the 2026–27 pages and are revised every year.
GATE Data Science and AI is one of the few GATE papers where a large share of the marks comes from mathematics rather than engineering — probability, linear algebra and calculus together carried between 32 and 42 of the 85 subject marks in the three official papers. That makes it unusually open to candidates from mathematics, statistics, electronics and electrical engineering. This guide answers the three questions such candidates ask: can I write it, will anyone admit me with it, and what do I have to learn from scratch?
1. Can you write it? Yes
GATE 2027 eligibility (official)
- Anyone in the third or higher year of any undergraduate degree, or who has completed a government-approved degree in Engineering, Technology, Architecture, Science, Commerce, Arts or Humanities.
- A 3-year B.Sc., B.A., B.Com. or BCA student is eligible in the third year or after completing it; an M.Sc., M.A. or MCA student from the first year; MBBS/BDS and some other degrees only from specified semesters (see the official table).
- There is no age limit, and no single GATE paper is restricted by degree discipline. A second paper, if you want one, must be an allowed combination (with DA: CS, EC, EE, MA, ME, PH, RA, ST or XE).
Eligibility to sit the exam is not the same as eligibility for a programme — see the next section.
2. Will a programme admit you? Check the degree rule, not just the paper
Admission has two gates: the GATE paper the programme accepts, and the qualifying degree it requires. A DA score is accepted widely by AI and data-science M.Techs, but some of them also require an engineering degree, and some accept an M.Sc. only in specific subjects.
| Programme | GATE paper | Degree rule (2026–27) |
|---|---|---|
| IIT Madras M.Tech Data Science & AI | DA only | All disciplines |
| IIT Hyderabad M.Tech AI | CS, EC, EE, DA, MA | Full-time B.E./B.Tech in any discipline, or part-time 4-year BS in Data Science, or full-time M.Sc. in Maths/Statistics/Applied Maths or equivalent (regular modes) |
| IISc M.Tech Computational & Data Science | DA among 14 papers | B.E./B.Tech (any discipline), M.Sc. (any discipline) or a 4-year B.S.; "a strong mathematical and programming background". A 3-year B.Sc. alone does not qualify. |
| IISc M.Tech Artificial Intelligence | CS, DA, EC, EE | B.E./B.Tech, M.Sc., 4-year BS/BS (Research), M.Math or M.Stat — and "a formal course in programming in C and C++" |
| IIT Guwahati M.Tech Data Science | DA, CS, EC, EE, IN, MA, ST, XE | Bachelor's or master's in a relevant discipline, CPI 6.0 (or 60%), and at least 6 years of education after Class 10 |
| NIT/IIIT programmes via CCMT | DA mapped at 67 institutes (194 programme entries, our count of the official CCMT 2026 seat-mapping tool, Sep 2026) | Mapped per qualifying degree — check your own degree in the seat-mapping tool |
Where other pages get this wrong
Writing GATE DA does not make you eligible for every AI M.Tech.
Commonly published instead: "Any graduate can write DA and get into an IIT AI programme."
Sitting GATE DA is open to any third-year undergraduate. Admission is not: IIT Hyderabad's M.Tech AI, for example, takes a B.Tech in any discipline or an M.Sc. only in mathematics, statistics or applied mathematics. A B.Sc. graduate should shortlist programmes by their degree rule first, and prepare for DA second.
3. What your degree already gives you
The grid below is our judgement of how much of each DA section a typical syllabus in each degree covers. It is a starting point for planning, not a rule — your own course may have been lighter or heavier.
| P&S | Lin. Alg. | Calculus | Prog./DSA | DBMS | ML | AI | |
|---|---|---|---|---|---|---|---|
| B.Sc./M.Sc. Maths | Good | Strong | Strong | New | New | New | New |
| B.Sc./M.Sc. Statistics | Strong | Good | Good | Some | New | Some | New |
| B.Tech ECE / EE | Good | Good | Strong | Some | New | Some | New |
| B.Tech Mech / Civil / Chem | Some | Good | Strong | Some | New | New | New |
| BCA / B.Sc. CS | Some | Some | Some | Strong | Strong | Some | Some |
| B.Tech CSE / IT | Good | Good | Good | Strong | Strong | Some | Good |
Darker = more of that section is typically covered. Our assessment of typical Indian curricula, not an official mapping — use it to spot your likely gaps, then confirm them with a past-paper section.
From our question-by-question count of the official papers. A strong mathematics or statistics graduate starts with a large share of the paper already in reach.
4. What to learn from zero, by background
Mathematics and statistics graduates
- Python: start in week one and practise daily. GATE tests it by output tracing — lists, slicing, loops, functions, recursion, simple classes.
- Data structures and algorithms: stacks, queues, linked lists, trees, hash tables; searching and the five sorts named in the syllabus; graph traversals and shortest paths. This is the biggest new block for you — 14 to 20 marks.
- DBMS & warehousing: ER and relational models, relational algebra, SQL, normal forms, indexing, OLAP. Entirely new, and 18 of 85 subject marks in 2026 by our count of the official paper.
- ML and AI: your statistics helps enormously (regression, naive Bayes, LDA, PCA are statistics), but search algorithms and logic will be new.
Electronics and electrical engineers
- Your calculus and linear algebra are usually enough; probability needs extending to statistics (confidence intervals, z/t/χ² tests, CLT).
- Python and data structures: you probably know some C — switch to Python early, because DA questions are written in it.
- DBMS and AI are entirely new; ML may be partly familiar from signal-processing electives.
Mechanical, civil and chemical engineers
- Calculus is your strength; linear algebra usually needs SVD, projections and quadratic forms added.
- Probability and statistics, programming, DBMS, ML and AI are all substantial new learning — budget the full nineteen weeks.
BCA and B.Sc. Computer Science
- Programming and DBMS are your strengths; probability, statistics and linear algebra at GATE level are the gap, followed by ML and AI.

Your first four weeks, if programming is new
A month to stop Python and data structures being the obstacle
- Week 1: Python types, lists, tuples, dictionaries, strings and slicing. Every day, trace ten short snippets on paper and check them by running them.
- Week 2: loops, functions, default arguments, recursion. Trace recursive functions by drawing the call stack.
- Week 3: stacks, queues and linked lists implemented in Python; linear and binary search, including the off-by-one cases GATE likes.
- Week 4: the five sorting algorithms in the syllabus, tracing each pass by hand; then trees and a first look at BFS and DFS.
Run this alongside the mathematics you already know, not instead of it. A measurable target for the end of October: at least 20 of the 31 programming questions in the three past papers (listed in our previous-papers guide) solved correctly without the key.
A realistic time budget
| Background | Mostly revision | Mostly new | Suggested weekly split |
|---|---|---|---|
| Maths / Statistics | P&S, linear algebra, calculus | Python, DSA, DBMS, AI | New material 65%, maths 20%, GA 15% |
| ECE / EE | Calculus, linear algebra | Statistics, DBMS, AI, Python DSA | New material 60%, maths 25%, GA 15% |
| Mech / Civil / Chem | Calculus | Nearly everything else | Follow the full 19-week plan; start now |
| BCA / B.Sc. CS | Programming, DBMS | P&S, linear algebra, ML, AI | Maths 45%, ML/AI 30%, revision 10%, GA 15% |
For the week-by-week schedule, see the GATE DA October-to-February plan; non-CS candidates should keep its mathematics-first order but start Python on day one rather than in week seven.
Practise it, don't just read it
Start with the section that is newest to you — a ten-question quiz shows within minutes whether it really is new.
The ProSyllabus GATE DA library currently has three topic quizzes: Matrix Rank and Inverse (Section 2, Linear Algebra), Backpropagation in Neural Networks (Section 6, multi-layer perceptrons) and Gradient Descent Variants (optimisation practice for Machine Learning — the syllabus names no gradient methods, though a 2026 question applied an SGD update). Each has ten questions and a worked explanation for every option. Probability, programming and DBMS have no quizzes yet — drill those from the section index of the official papers.
Can a non-CS student write GATE DA?
Yes. GATE 2027 has no discipline restriction on any paper: anyone in the third or higher year of an undergraduate degree, or who has completed a degree in engineering, technology, science, commerce, arts or humanities, can write DA.
Can a B.Sc. Maths or Statistics student write GATE DA?
Yes, from the third year of a three-year B.Sc. Mathematics or statistics graduates start with an advantage, because probability, linear algebra and calculus carried 32 to 42 of the 85 subject marks in the official 2024 to 2026 papers. Check each programme's degree requirement before applying for admission.
Is GATE DA good for ECE students?
Often, yes. ECE graduates usually have the calculus and linear algebra, and several AI and data-science M.Techs accept both DA and EC. The main new material is statistics, databases, data structures in Python, and AI.
Which programming language is used in GATE DA?
Python. The official DA syllabus specifies programming in Python, and all three past papers included Python output-tracing questions.
Do all IITs accept non-CS graduates with GATE DA?
No. The paper is accepted widely for AI and data-science M.Techs, but each programme sets its own degree rule. IIT Madras's M.Tech in Data Science and AI accepts all disciplines, while IIT Hyderabad's M.Tech AI accepts a B.Tech in any discipline or an M.Sc. in mathematics, statistics or applied mathematics.
