Background Information:
I founded "Ctanujit Classes" in July, 2013 for supporting students preparing for ISI, CMI, TIFR, IIT, and IGIDR Entrances. I was involved in teaching (both online and offline) Mathematics & Statistics for almost 5 years (2013 to 2018). Over 100 of my students got admission in various Bachelors' and Masters' courses at Indian Statistical Institute, Chennai Mathematical Institute, Indian Institute of Technology, Indira Gandhi Institute of Development Research, and Delhi School of Economics. With the experience of teaching I have written two very handy books (Challenging Mathematical Problems for ISI CMI 10+2 Exams and Solving Mathematical Problems for ISI MS & MTech Exams) for aspirants which is published and distributed by Ctanujit Classes. These books will be helpful for your preparation of Bachelor's and Master's entrances of ISI, CMI, IIT, TIFR, IGIDR, and others.

These books are only available in hard copies (hard cover binding book). 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 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 CMI BSTAT and BMATH entrance tests containing 1100+ Solved Problems (500+ Objective Solved Problems and 500+ Subjective Solved Problems). The problems are mostly taken from past ISI, CMI, and Mathematical Olympiad papers.
2. Solving Mathematical Problems book contains 1000+ solved problems (500+ Objective Solved Problems and 500+ Subjective Solved Problems) on Mathematics, Probability, and Mathematical Statistics. It will be highly useful for the motivating students preparing for ISI MSTAT/MMATH/MSQE/MSQMS/PGDBA/MTECH entrances as well as IIT JAM Mathematics/ Mathematical Statistics, TIFR and CMI MS exams.
