My teaching philosophy extracts itself from the saying,
"Teaching and Education are not one size fits all" and
"Good teachers show you where to look but don't tell you what to see".
That's why my main goal in any teaching endeavor is to encourage the students to ask the basic fundamentals of Mathematics and get them answered in an innovative and interactive way making maths a creative part of their lives and not a burden.

Since theory and practice are intricately linked, I emphasize both to truly nurture the student's understanding of the subject.
I believe in a two-way learning process, much as I hope my students would learn from me, I equally appreciate learning from them as well which helps me to understand that each student learns differently so I constantly reflect on my own teaching styles and try to incorporate every child's inputs to provide them with best-personalized education experience using real-life examples, case studies, dialogues and diagrams.
Hence, "Teach me I will forget, Show me I will remember, Involve me I will understand" is what I have learned and is what I impart.

Explains concepts easily through various examples

Sunil Sir is currently teaching me Linear Algebra from scratch and within a few days, I'm already so much more confident in the topic. I am able to think about and understand ideas in a more abstract manner. Sir is also extremely patient and explains concepts from different perspectives if needed.
I cannot thank Sir enough for his help so far. Would definitely recommend him for any math help.

Knowledgeable Flexible and Extremely Attentive Teacher

Mr. Sunil was an outstanding teacher who helped me in Linear Algebra. He provided very flexible timings that allowed me to receive the help that I needed. Mr Sunil was also extremely knowledgeable and helped explain concepts such as diagonalizability that I was initially struggling with.

This review of concepts along with helping with practice problems best prepared me for my exams. I felt confident in my results and was able to acheive an outstanding grade thanks to Mr. Sunil. I strongly reccomend Mr. Sunil and i hope to learn from him in the future.

Excellent and Knowledgable Teacher

I'm studying Analysis from Sunil, and his teaching methods are really good. He is super passionate about the material and helps clarify any doubts. He is also really friendly and makes the classes really enjoyable.
He makes sure you understand everything, and helps work through practice problems and exercises to make sure you understand the content well.
He was also really patient, and is willing to reexplain or work through any explanations again to help you fully understand.
Also, he is very good at explaining the intuition and the ideas behind the concepts.
One of the best tutors who is extremely knowledgable in the subject matter and would highly recommend for any course.

Best Tutor for any student interested in College Level Mathematics Courses

Sunil Sir's teaching methods are excellent. They are apparent and concise. He is a very thoughtful teacher who puts a lot of thought into how he presents the material. He helped me understand the complex concepts of many college courses like Probability and Statistics, Multivariate Calculus and Discrete Mathematics in a convenient and practical method. He was quickly able to help me understand and solve my assignment questions in these courses. His lessons were engaging, timely, and he was very patient with me, always encouraging me to try. He is one of the best tutors that I've had. I highly recommend him to anyone who is studying or interested to study College level Math Courses.

He is competent about his subject well and teach in methodical way understanding exiting gap between student knowledge and level need to reach.
No rush but explain in detail and get done the thing through student than simply providing solution. This build up student confidence. .
