I am Arijit Pramanik, currently pursuing my Masters of Science (MS) in Computer Science at University of Wisconsin-Madison. I graduated from IIT Bombay with a
Bachelors degree in Computer Science and Engineering. I was also the state topper from West Bengal in NSEC 2015. I am also a KVPY SA stream scholar and NTSE scholar.

I would like to express my humble gratitude to Koley sir for his exceptional teaching and guidance during my JEE preparation.

Chemistry is a subject with a vast syllabus divided orthogonally into Physical, Inorganic and Organic Chemistry. It is highly-scoring given that you make a systematic study of all exceptions besides general theory. Organic chemistry is a subject where if you know the mechanisms well enough, you can solve almost all problems. Sir used to generalize and explain the mechanisms so well that you could picture them during your JEE Advanced exam which helped evoke further interest in that subject. Regular practice problems given by sir after careful explanation of each concept, helped me a lot. He was always available and could also be easily approached with any doubt.

The material and practice problems provided by sir, interspersed with previous year JEE questions helps to get an equally better grasp at all of the three chemistry branches. He prepares you very well and hence I would recommend all JEE aspirants to join him for Chemistry preparation. I would once again like to sincerely thank sir for all his painstaking efforts during my JEE preparation and for his contribution to my success. I wish him all the very best for his future ventures.

This is Shiladitya Gangopadhyay, final year student at Department of Electronics and Communication Engineering, NIT Allahabad. I will be joining Oracle India as a fulltime from July 2020.

It goes without saying that Chemistry is strategically a very important subject to ensure a good rank in any competitive exam, which can't happen without a dedicated teacher who has very strong forte on the subject. Not only did Tapas Sir teach every topic, small or big, with absolute command and dedication, but made us solve a plethora of problems, across Organic, Inorganic and Physical Chemistry. Specially considering how tough Organic Chemistry is, he covered all reactions and mechanisms that could possibly be there with ease, at a very good pace, made sure we understood everything, and also ensured all of my doubts were cleared whenever I wanted to. He meticulously guided every student, and his guidance will surely help thousands of others to come, be it for JEE, Olympiads, or KVPY.

I am Akash Mandal. I am currently studying Mathematics and Computing at IIT Kharagpur. I secured a rank of 1270 in JEE Advanced, 9 in WBJEE, and 1 in KVPY.

I would like to express my gratitude to Koley sir for his excellent teaching and able guidance during my preparation for JEE.

Chemistry is undoubtedly the most extensive subject in terms of the JEE syllabus, with organic, physical and inorganic being completely different ball games. Conceptual understanding of each topic, as opposed to rote learning, is necessary to tackle JEE problems. And for that, there is none better than Koley sir. He goes at just the right speed, explaining every detail, every problem, meticulously, and making sure that the concept is understood properly. Sir's friendliness makes him easily approachable.

Sir's dedication, brilliance, and focus are unmatched when it comes to JEE preparation. I remember his ability, in particular, to quote (and recognize) previous years' JEE chemistry problems from the back of his head along with year as well as options(for MCQ). My personal favourite classes would be when sir taught reaction mechanisms. Sir explained the logic behind each and every step and would always have answers for any doubts we had. I would absolutely recommend any aspirant to opt for Koley sir for JEE Chemistry preparation.

I would like to sincerely thank sir for playing a central role in helping me achieve whatever I have achieved and will achieve in the future. Apart from being a great teacher, sir is a great human being. I would like to convey my best wishes to him in all his endeavours.

I am Srijit Dutta, currently working as R&D engineer at Samsung Electronics, South Korea. I graduated from IIT Bombay in 2019 with a degree in Computer Science and Engineering. I secured a rank of 75 in JEE Advanced 2015. I would like to thank Koley Sir for his guidance and extraordinary contribution during my JEE preparation to help me to succeed in JEE Advanced. Among PCM, Chemistry is undoubtedly the one with the vastest syllabus, with Physical, Organic and Inorganic Chemistry being completely different from one another. Sir approaches each of these fields in a way that requires no rote learning. Sir explains all details meticulously with dedication which ensures that students understand the concepts behind a topic, which in turn helps them to solve any related problems. He provides examples and practice questions after each topic which helped me to understand it better. Sir explains each and every step behind any reaction, be it organic or inorganic, which makes it easy to understand how the products are formed. Sirís friendly nature makes him very approachable. You can approach him with any difficulties you are facing and he takes time out of his schedule to help you. I would absolutely recommend any aspirant to join him for JEE Advanced/KVPY/Olympiad preparations. I would like to sincerely thank Sir for all his efforts during my JEE preparation and for his contribution to my success. I would like to convey my best wishes for all his ventures.

I am Sombuddha Chakravarty. I am a final year undergrad student studying Electrical and Electronics at BITS Pilani. I had scored 378 in BITSAT and ranked 5248 in JEE Advanced, 104 in WBJEE, 302 in NEST and I cracked KVPY twice(class 11 and 12) in with AIR 635 and 658.

I am extremely grateful that I got Koley sir as my chemistry teacher during my JEE preparations. As most of you know, the Chemistry syllabus for JEE is extremely vast but at the same time, Chemistry can help you significantly improve your ranking provided your concepts are clear. When it comes to Chemistry, speed and accuracy are of the essence and Koley sir covered each aspect very well.

I am Aniruddha Mahapatra. I am currently studying Computer Science and Engineering at IIT Roorkee. I secured a rank of 1683 in JEE Advanced and 480 in KVPY.

This gives me a nice opportunity to express my gratitude to Koley Sir for his excellent teaching and guidance that have helped me immensely in securing a good rank in many competitive exams during the 12th standard.

When it comes to achieving a good rank in competitive exams, Chemistry is a key subject. However, considering the diversity in the syllabus only rote learning will not get one far, especially in organic chemistry. It requires a conceptual understanding of every topic to solve the complex problems in JEE. I believe, Koley Sir is one of the best tutors for this purpose.

I am Rajorshi Ram, 1st year student at NRS Medical College. I was taught by Tapas Koley Sir during my NEET preparation. He has an in - depth knowledge in all the topics and was always available for doubt clearings. He has a unique way of teaching followed by a variety of questions and I am indebted to him for his dedication in helping me pursue this dream of mine.
