Cheenta. Passion for Mathematics.
Pause for a moment. Let us divide letters by letters!
What if you wanted to divide the base by an exponent? This situation comes up quite often in Elementary Number Theory. Consider the following equation:
$$ \displaystyle{ k! + 48 = 48 \times (k+1)^m } $$
Can you show that k divides m? The answer is hidden somewhere in our library articles.
What is Cheenta?
Cheenta delivers outstanding programs in Mathematics for Olympiads, I.S.I. & C.M.I. Entrance and College.
Since 2010, we have worked with hundreds of students from India, United States, UK, Australia, Singapore and Middle East
All of our classes are delivered exclusively live and online. Our main center in Calcutta (India) office hosts a reading facility for advanced learners.
Who are Teaching?
We have exOlympians and outstanding researchers who teach out of love for the subject.
In India: Indian Statistical Institute, Chennai Mathematical Institute, IISER, TIFR, Calcutta University, IIT KGP
Outside India: the University of Wisconsin Milwaukee (USA), University of North Carolina (USA), St. Louis University (USA), IMPA (Brazil), E’Cole (France)
Admission and eligibility
Admission to a Cheenta program is highly selective. The prospective student must first go through a trial class.
Our courses are significantly more intense than regular school or college programs. Apply only if you are thrilled by the beauty of mathematics.
Math Olympiad, I.S.I. Entrance and College Mathematics candidates form the core student body of Cheenta.

Training brilliant minds.
Since 2010.
Cheenta has worked with brilliant maths and science olympiad students from over 6 countries. Our courses are specifically geared toward students with an exceptional interest in Mathematical Sciences.
Math Olympiad
Outstanding mathematics program for deserving school students.
PreOlympiad Thousand Flowers
For children who are starting out in Mathematics and Science.
I.S.I. & C.M.I. Entrance
For B.Stat and B.Math entrance at Indian Statistical Institute, B.Sc. Math at C.M.I. & KVPY.
College Mathematics
For I.S.I. M.Math, Mathematics Subject GRE, TIFR; Groups Analysis, Topology and more
I.S.I. & C.M.I. Entrance
B.Stat, B.Math Entrance at I.S.I. and B.Sc. Math Entrance at C.M.I. require special training in Number Theory, Geometry, Combinatorics and Algebra (apart from regular High School topics).
Problems from standard topics such as Calculus, Trigonometry or Coordinate geometry can significantly tricky.
Advanced Topics
Number Theory, Combinatorics, Algebra, and Geometry at Olympiad standard are both necessary and useful components of this course.
Regular High School Topics
Advance problems from Calculus, Trigonometry, Coordinate Geometry and Algebra are bread and butter for handling more complicated ones.
Not a spectator sport.
Think about the interesting problem!
College Mathematics
An advanced program for College Students as well as adults interested in modern mathematics. This program is useful for I.S.I. M.Math Entrance, Subject GRE, IIT JAM and similar entrances.
We work on Groups, Rings, Fields, Linear Algebra, Analysis, Topology and other advanced topics. As usual problem solving remains the driving force of the program.
The hyperbolic 3 space may come up in this course. Behold this beautiful Hyperideal Honeycomb created by Royce3 (under creative commons).
Continuing Education
Many adults, who are pursuing jobs or industry, have taken this program. A curious mind, coupled with a determination to take up challenges is sufficient.
Advanced GRE, TIFR, M.Math
This program is for the true math fanatic, who yearn to understand the anatomy of ‘reason’ a little better. Advanced problemsolving session every week!

Testimonials…
“a wide range of mathematical topics, and every lesson is packed with insights and methods. We are extremely pleased with the difference he has been making. Under his tutelage Sam has secured several gold awards from the UK Mathematics Trust (UKMT)and Scottish Mathematical Council (SMC).”
Jayanta Majumdar“Shuborno has been studying under Ashani from last one year. During this period, we have seen our son grow both intellectually and emotionally. His concepts and approach towards solving a problem has become more mature now. Not that he can solve each and every problem but he loves to think on the tough concepts. For this, all credit goes to Ashani, who is never in a hurry to solve a problem quickly. Rather he tries to slowly build the foundation..”
Shubrangshu Das“Our experience with Cheenta has been excellent. Even though my son started in Middle School, they understood his Math level and took personal interest in developing a longterm plan considering his strengths and weakness areas. Through out the semester courses they have nourished him with challenging problems and necessary homework. His guidance has helped my son to perform well at competitions including USAJMO and others. He has grown more confident in his math abilities over the past year and half and is hoping to do well in the future.
I am impressed with their quality and professionalism. We are very thankful to Cheenta and hope to benefit from them in the coming years. I would strongly recommend them to any student who wants to learn Math by doing challenging problems, specially if they are looking for Math than what their school can offer.”
