Core Data Science and AI

Machine Learning and AI carry a large share of the GATE DA paper and are what set this branch apart. These notes cover regression, classification, clustering, neural networks and the AI search and reasoning methods. Download below.

Mathematical Foundations

Mathematics is the biggest block in GATE DA, with Probability and Statistics alone worth close to a quarter of the paper. These notes cover probability, statistics, inference, linear algebra, calculus and optimization. Download each topic below.

Programming and Databases

Programming and databases together carry a steady, high-return share of the marks. The notes cover Python, data structures, algorithms, DBMS, SQL, normalization and data warehousing. Download each topic below.

Complete Revision

These pull the whole syllabus together for the final push, with an all-in-one complete-syllabus notebook and a formula, shortcuts and exam-checks book for the last few days. Download each below.

General Aptitude

General Aptitude is a fixed 15 marks in GATE DA and is among the easiest to score. It covers verbal ability, numerical reasoning, data interpretation and logic. The same notes work for GATE DA as for any other branch.

GATE DA Exam Pattern and Weightage

The GATE DA paper has 65 questions for 100 marks in three hours. General Aptitude is a fixed 15 marks and the technical part carries the other 85. Mathematics is the largest technical block, with Machine Learning, Programming and Databases close behind.

• General Aptitude: 15 marks, fixed in every paper.
• Probability and Statistics: the single largest area, close to a quarter of the paper.
• Machine Learning and AI: a major, branch-defining block.
• Programming, Data Structures and Databases: steady, high-return marks.

Which Topics to Revise First

Start with the biggest and most connected areas. Probability and Statistics returns across Machine Learning, so revising it first pays off twice. Programming and databases are quick to score once the basics are firm.

• Lock down Probability and Statistics early, since it feeds Machine Learning.
• Keep Linear Algebra and Optimization close, as they support most models.
• Give steady practice to Machine Learning and Python.
• Do not leave General Aptitude for the last day.

How to Use These Notes

Use each PDF as a theory and formula base beside daily practice. Read a topic, note its key results, then solve previous year questions on it. Before mock tests, the complete-syllabus book and the formula book make revision fast for students.
