“I know numbers are beautiful. If they aren’t beautiful, nothing is.”

Paul Erdos 

Welcome to the exciting world of mathematics beyond the school curriculum.

**New: Combinatorics Problem: Round Robin Tournament

In our advanced mathematics classes, problem solving is the key driving force. We delve deep into ideas from Geometry, Number Theory, Combinatorics and Algebra, all the time appreciating their beautiful interconnections.

We like to call ourselves, artisans of mathematics. Our learning process is deliberately slow. We believe that nothing worth doing can be done ‘quickly’.

Each student is a different person, with distinct strength and abilities. One crude classification is: some are good with visualization, others are more comfortable with algebraic manipulations. Hence we create a deeply personalized experience for each student, which in our opinion, is a rare thing in the world of Math Olympiad training. This personalization coupled with problem driven discussion are the key features of our classes. 


  • Advanced Math Olympiad Program

Here are some details about it:

  • Mode: One on One program
  • Frequency: 4 hours of online, live, interactive classes every week
  • Duration: Students typically work for, 3 to 4 years through their school life.
  • Minimum Subscription: 140 hours for $3220 (at $23 per hour)

This program is useful for:

  • American Mathematics Contests (AMC 8, 10, 12)
  • American Invitational Mathematical Examination (AIME)
  • IMO
  • Duke Math Meet

Admission Process

Note that admission is highly selective (only 10 students are admitted in each year). The prospective student must attend a trial class and test first. Contact me using the above contact information for scheduling a trial session.

What my students say:

My son, 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 of the students by discussing even minute concepts. His style of teaching is also unique combining different concepts and giving mathematics a more holistic approach. He is also very motivating and helpful. We are lucky that our son is under such good guidance. Rare to get such a dedicated teacher.


We contacted Cheenta because our son, Sambuddha (a.k.a. Sam), seemed to have something of a gift in mathematical/logical thinking, and his school curriculum math was way too easy and boring for him. We were overjoyed when Mr Ashani Dasgupta administered an admission test and accepted Sam as a one-to-one student at Cheenta. Ever since it has been an excellent experience and we have nothing but praise for Mr Dasgupta. His enthusiasm for mathematics is infectious, and admirable is the amount of energy and thought he puts into each lesson. He covers 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). Recently Sam received a book award from the UKMT and got invited to masterclass sessions also organised by the UKMT. Mr Dasgupta’s tutoring was crucial for these achievements. We think Cheenta is rendering an excellent service to humanity by identifying young mathematical minds and nurturing them towards becoming inspired mathematicians of the future.
