Cracking the ISI M.Tech CS Entrance exam is comparably easier than securing a top rank at GATE. The advantage lies in solving the subjective questions where you will be allotted more time than what is in GATE. It offers around only 3 mins per question.

In case of the ISI Entrance Exam, it consists of two papers,

• MMA: This paper consists of the MCQs on mathematics. Mainly, there are 30 questions that are to be solved within around 2 hours. You should be familiar with the undergraduate mathematics level questions. Here are some top recommended books for better preparation,
• Test on Mathematics at the 10+2 level:Published by ISI, this book is renowned among everyone as “TOMATO”. This book is a great compilation of a variety of questions, alongside previous year entrance exam questions for both B.Stat and B.Math. 
• Higher Algebra by Hall & Knight (Arihant): It effectively helps to prepare for the algebra part.

• PCB: This paper, out of others, is rather subjective. It has 4 math questions, including proofs from algebra and questions from the calculus section. Moreover, there are other 5 questions from the elective you opt for; such as computer science, statistics, physics, engineering and technology, mathematics, and more.
