The syllabus is very important to crack any competitive exam. Without knowing the syllabus we can not prepare well for any exam. If we want to prepare for any exam, first we need briefly examine a particular subject syllabus and paper pattern.
Latest Gate CSE and IT (Revised) syllabus new updated
Section 1: GA – Genral Aptitude
Basic English grammar: tenses, articles, adjectives, prepositions, conjunctions, verb-noun agreement, and other parts of speech
Basic vocabulary: words, idioms, and phrases in context Reading and comprehension Narrative sequencing.
Data interpretation: data graphs (bar graphs, pie charts, and other graphs representing data), 2- and 3-dimensional
plots, maps, and tables.
Numerical computation and estimation: ratios, percentages, powers, exponents and logarithms, permutations and
combinations, and series Mensuration and geometry
Elementary statistics and probability.
Logic: deduction and induction Analogy, Numerical relations and reasoning
Transformation of shapes: translation, rotation, scaling, mirroring, assembling, and grouping
Paper folding, cutting, and patterns in 2 and 3 dimensions.
Section 2: Engineering Mathematics.
According to the gate computer science council, the engineering mathematics section is the same as all engineering branches but follows the mathematics syllabus for mainly computer science branch students.
Discrete Mathematics: Propositional and first-order logic. Sets, relations, functions, partial orders, and lattices. Groups. Graphs: connectivity, matching, coloring. Combinatorics: counting, recurrence relations, generating functions.
Linear Algebra: Matrices, determinants, the system of linear equations, eigenvalues and eigenvectors, LU decomposition.
Calculus: Limits, continuity and differentiability. Maxima and minima. Mean value theorem. Integration.
Probability and Statics: Random variables. Uniform, normal, exponential, Poisson, and binomial distributions. Mean, median, mode, and standard deviation. Conditional probability and Bayes theorem.
