NPTEL – Learn from the best

National Programme for Technology Enhanced Learning is one of the best online resources for leaning from the best faculty in India. For preparing GATE, there are courses for almost all subjects. Following list courses can be pretty useful for your preparation, apart from the standard textbooks itself. Main advantage is you can fast forward the things you know, while repeatedly listen concepts that are difficult!

Subject	Lectures	Teacher
Data Structures and Algorithms	36	Prof. Naveen Garg
Discrete Structures	40	Prof. Kamala
Computer Networks	40	Prof. Sujoy Ghosh
Computer Architecture	38	Prof. Anshul Kumar
Design and Analysis of Algorithms	34	IIT B Faculty
Software Engineering	39	IIT B Faculty
Database Design	43	Prof. Srinath, Prof. Janakiram
Digital Circuits and Systems	40	Prof. Srinivasan
Mathematics II	24	IIT Roorkee
Numerical Analysis and Computer Programming	38	Sunil Kumar

I loved the way Prof. Naveen Garg teaches DS and Algos. Absolutely amazing way to explain things. There are many other courses not mentioned here that you might want to try too. Best Luck!

Preparing Maths for GATE, CS

Maths part for CS GATE plays a very crucial role in the overall outcome, and I think it is the most important and easiest subjects in the over all syllabus. Even here in IIT K, we are required to take a basic course in maths and algorithms, as the general belief is: “Engineering Maths is not studied as well as it should in most of the universities” I will try and jot down some points that could help in Maths preparation.

Syllabus

• Mathematical Logic
• Probability
• Set Theory & Algebra
• Combinatorics
• Graph Theory
• Linear Algebra
• Numerical Methods
• Calculus

Books that can be useful

1. Discrete Maths – Kenneth Rosen

2. Higher Engineering Maths – B.S.Grewal

3. Probability and Random Processes – Geoffery Grimmet

My personal opinion:

G.S.Grewal is useful for basic probability, numerical methods and calculus. Kenneth Rosen is pretty comprehensive for all other topics. The third book will take you very deep into probability theory, which will always be helpful for future, but might not be exactly required for GATE.

Hope this helps. Feel free to post any feedback / queries. Will try and update the blog more frequently in coming weeks! Laters!
