GATE CS or GATE DA: the syllabi compared

If your degree allows you to sit either Computer Science and Information Technology (CS) or Data Science and Artificial Intelligence (DA), you will find no shortage of pages telling you which to choose. Nearly all of them argue from something they cannot show you: which paper is easier, which has better prospects, which is safer. Nobody outside the organising institute knows the first, and the second and third are claims about employers and institutes that those organisations publish themselves. What CAN be shown is the pair of documents. This page prints them against each other and stops there.

The shape of the two papers

The CS syllabus declares 10 sections in about 362 words; DA declares 7 in about 351. The section lists diverge immediately. CS opens with one section called Engineering Mathematics that contains Discrete Mathematics, Linear Algebra, Calculus, and Probability and Statistics together. DA has no section called Engineering Mathematics at all: it spends its first three sections on Probability and Statistics, Linear Algebra, and Calculus and Optimization as separate sections. That is the same territory, taken at greater length and without discrete mathematics. The brochure also lists DA among the papers with no separate Engineering Mathematics allocation on printed page 4.

Section by section

Term by term

Section titles are coarse: “Machine Learning” as a section title tells you less than whether the word “regression” appears anywhere in the other paper's document. The table below asks one narrow question of each PDF — is this term named in it? — and answers it by searching the file. Read the note beneath the table before you draw anything from it.

Is the term named in that paper's syllabus?

What the table shows, said carefully

Four things, and only these four. The shared spine is real: Linear Algebra, eigenvalues, probability, Bayes, the Poisson distribution, graphs, data structures, algorithms, databases and optimisation are named in both documents. The statistics DA names and CS does not are the inferential ones — the central limit theorem, confidence intervals, the z-test, the t-test and the chi-squared test. The systems half is CS's alone: operating systems, computer networks and compiler design are named in the CS syllabus and in no part of the DA syllabus. And machine learning, with the AI section behind it, runs the other way. That is the difference between the two documents. It is not a ranking.

You may be able to sit both

CS and DA are an allowed two-paper combination in GATE 2027: Table 4 on printed page 13 lists DA among the papers allowed as a secondary paper with CS, and CS among those allowed with DA. The brochure labels that table “Tentative, Subject to change”, and that label is part of the fact. Sitting two papers is a separate decision with its own fee and its own two sessions, and the shared spine in the table above is the reason the pair is on the list at all.
