Background Information: 

I founded "Ctanujit Classes" in July, 2013 for supporting students preparing for ISI, CMI, IIT, DSE and IGIDR Entrances. I was involved in teaching (both online and offline) Mathematics & Statistics for four years (2013 to 2017). Over 100 of my students got admission in various Bachelors' and Masters' degree courses at Indian Statistical Institute, Chennai Mathematical Institute, Indian Institute of Technology, Indira Gandhi Institute of Development Research, and Delhi School of Economics to name a few. Here is a LINK to know more about alumni of Ctanujit Classes. From 2018, I stopped giving tuitions and may not continue it in near future as well.  

With the experience of teaching, I have written two convenient books (Challenging Mathematical Problems and Solving Mathematical Problems) for aspirants. These books will be helpful for your preparation of Bachelor's and Master's entrances of ISI, CMI, and IIT. 

Important Note: I am NOT offering any private tuition classes now. Please don't send me mail for private tuition. ​
​
Description of the Books: 

These books are only available in hard copies (hardcover binding books). So please do not request for soft copies. You can purchase these books from anywhere in India. The content of these books are based on ISI/CMI/IIT Entrance Test's Papers and over 1000+ solved problems (problems with detailed solutions) are given in these two books. I have given almost 50% Objective and 50% Subjective problems in each of these two books.
​

​1. Challenging Mathematical Problems book is useful for all the students preparing for ISI BSTAT & BMATH and Mathematical Olympiad Exam containing 1000 Solved Problems (approx. 500 Objective Solved Problems and 500 Subjective Solved Problems). To download the content of the book click HERE. The cost of the book is Rs. 1000 (One Thousand Rupees)  which includes hard cover binding, waterproof packaging and delivery charges.
