Hi folks. 

 I am Paras Chopra (AIR-2 GATE DA), and here I am sharing the resources that helped me prepare for the exam. Before we begin, let me give you a brief overview of my background : I hold a B.Tech degree in EE and have 3 years of work exp. 

I left my job to prepare for UPSC and later for the GATE exam. My GATE DA preparation took around 7 months but I must confess that I had a strong background in Maths even before starting my prep. I have also taught Calculus and Statistics to students to earn a side-income, and you can find some of those lecture slides and videos below. 

Additionally, I would like to thank Piyush Wairale sir, whose courses helped me to cover the DBMS & Warehouses and AI portion of the syllabus in a short time. Now let’s move on to the resources: 

 #1 : Programming, Data Structures and Algorithms: 

 ● Lectures by Prof. Sriram Sankaranarayanan on Coursera: Course#1 : Algorithms for Searching, Sorting, and Indexing Course#2 : Trees and Graphs: Basics 

 ● My notes from the above course : DSA notes 

 ● Additional resource : DSA book- you can find free pdf online 

 #2 : Database Management and Warehousing:

● Online course by Piyush Wairale : https://www.piyushwairale.com/ 

 ● Lectures by Prof. Di Wu on Coursera: Course#1 : Relational Database Design Course#2 : SQL 

 ● Notes from above courses: DBMS notes 

 ● Reference books : Not necessary (above materials are sufficient for GATE) 

 #3 : Machine Learning: 

 ● Stanford University Machine learning course : Andrew Ng Machine Learning ● Statistical Learning course by Trevor Hastie, Rob Tibshirani : ISLP (Study only those topics relevant to the syllabus) 

 ● Notes from above courses: ISLP course slides ● Reference books : Not necessary (above materials are sufficient for GATE) 

 #4 : Artificial Intelligence: 

  ● Piyush Wairale AI online course : www.piyushwairale.com 

 ● All questions in this year’s paper could be solved from the above course. Nothing more is needed.

 ● Notes from the above course: AI notes 

 #5 : Linear Algebra: 

 ● Linear Algebra course by Prof. Gilbert Strang MIT : LA Gilbert Strang (Lecture 11, 12 and the last five lectures are not in syllabus and can be skipped) 

 ● Notes from the above course : MIT OCW Lin.Alg notes 

 ● Practice problems from the course page or Prof. Strang’s textbook. 

 #6 : Calculus: Any good online course can be used to learn the basics. This playlist was recorded by me while teaching JEE aspirants but it can be used for GATE preparation as well (except for some parts of lecture 3) Course playlist : Calculus playlist 

 #7 : Probability and Statistics: I had taught Statistics to a student preparing for the AP exam and found the textbook “The Practice Of Statistics 5th Edition - Daren Starnes” excellent. For those having sufficient time, I would suggest using this textbook for the GATE DA exam. Lecture notes for the same can be found here : Statistics Lecture Notes

Additional points : 

 ● The Coursera courses mentioned above can be watched for free, but you can buy a subscription to access graded assignments and get a certificate. You can check out the financial aid option in case you do not have money but still want to do the assignments.

 ● The above resources can be studied and revised within six months if you study daily for 6 hours.
