Very organised and well structured

I've had a few lessons with Tanoy now and seen huge improvements in my Tableau capability! Would highly recommend him to anyone wanting to learn/improve their skills in this area.  He is very patient and understands the topic incredibly well. He has an obvious grasp of the material and always been able to answer any questions I put to him.  The lessons are organised in a very precise format and well laid out, with live examples and homework. Saying that,  one of the reasons I took the lessons is to prepare for a Tableau exam and he was able to tailor the lessons to suit the requirements and prepare me for it.  He's very responsible  and highlights any bad practices.  I found the lessons very beneficial and would definitely recommend it.

Great Explanation !!!

Tutoring with Tanoy is such a remarkable learning experience. He is without a doubt an expert in what he is teaching and shows great knowledge of the subject by giving lots of examples. Not only does he take the time to ensure that you understand the concept but he also makes sure that you speak of any doubts/ask any questions that might bring miscomprehension of the subject matter.He is also willing to give advice on any subjects related to what you are learning. All that make him a good listener and an interactif tutor.He is one to tutor with.
