Mentor of Quants, DI and LR for CAT, XAT, GMAT, GRE, Placement.

I have known sir for 2 years now. Sir is amazing in terms of explaining, subject knowledge, etc. Apart from academic help, you can talk to him about any other issue like career options or help with interviews. He is always happy to help.

he is outstanding

An excellent teacher with illustrious background and teaching methodology.
Can engross the students with his lectures and generate both interest and enthusiasm among them towards the subject. For Aptitude skill training he is associated with premier colleges including IIT, KGP.
One of the best teacher and respectable person with a high sense of regularity and punctuality.
I give 5 * to him.

Teaching skill is excellent the way he teaches is very easy to understand

Sanjay sir taught me for a year. He makes the concepts extremely simple to understand and his friendly nature creates a very engaging environment during the knowledge sharing sessions. Sir is undoubtedly one of the best professors I have been taught by.

SKD sir as we lovingly call him is a gem of a person. He has not only developed unique ways to teach but also encourages his students to pursue sums in their own style and then rectifies when needed. He helps bring out the best in every student and Is very approachable online as well as offline.
Lucky to have him as my mentor

He has excellent concepts and teaches from the basics. He is friendly with the students and takes a lot of effort to help them clear their doubts. He is genuinely interested in helping out the students.

I have known Mr. Sanjay Kr for a few years now. What stands out is that besides having an astonishing command over mathematics and aptitude topics, he has a unique delivery methodology based on the lines of story narration.
I think superprof is a subtle title for a man of his stature.

Teaches the toughest of concepts in a simple,beautiful and most importantly comic way :D .Instead of teaching formulaes, he teaches the idea and intuition behind them.So the next time you forget the fomulae, you can always recall them easily.Teaches Quantitative aptitude extremely well.

Sanjay has been associated with Globsyn for almost a decade.He is dedicated,sincere and very thorough in his subject.He is extremely patient and understanding with the students and they just love to attend his lectures.He has really made a visible difference to the learning of our students.

Being a student of Sanjay Sir has always been a great pleasure for me. His humorous and passionate way of teaching not only keeps the class entertaining but also motivates his students to be in love with the very subject. He is never impatient, always helpful and by all means a perfect guide that we seek for.

I am Shubhankar Mondal. I took aptitude classes from Mr. Sanjay Kr. Datta during 2014-15 from Gateforum Kolkata South Campus.
I will regard him not as ‘one of the’, but ‘the best’ aptitude professor I ever came across.
With an ocean full of experience and his non-conventional, creative, and practical approach to solving aptitude problems is a rare find.
I believe this platform is too less to describe him.
His way of approaching problems is something I would not term as easy or difficult, but the best part is he allows us to think through a different dimension. And over the last four years since being taught by him, I have felt that the different dimension of thinking is not only useful in solving aptitude problems, but it helps in solving real life problems too.
In addition to that, his humility and warmth shall always be an inspiration for me.
I graduated from IIM Calcutta in 2017 and I would regard his teaching as an indispensable contribution.
Sir, you will always be remembered. Hoping to see you soon.
Seek your blessings for a bright and successful professional career ahead.
With Best Regards
