Saravanan Nanthakumar Tutor, Electronics Engineering and Physics
30 Reviews
I am an independent researcher in Electronics Engineering and Physics. I hold a master's degree in engineering with specialization on Very Large Scale Integrated-Circuits (VLSI) Design. My area of interest in research spans Analog/Mixed-Signal/RF Circuits and Relativity in Physics.
I teach interactively. I ask the student to answer questions by intuition derived from the class, so that I have feedback of the student's understanding of the subject and teach accordingly. I receive direct feedback from students as well. I let the student speak and analyze the knowledge of the student in the concerned subject, to adapt the teaching strategy. I use different types of teaching strategy for students from a variety of background and mindset. I repeat explaining a concept, from all the possible viewpoints, until the student understands the concept that has been taught. I teach with variety of examples and illustrations to make the session mutually beneficial.

Best ECE Tutor - Honest, Sincere and Reachable
I am writing to commend Mr. Saravanan for his exemplary instruction in ECE subject (Digital Systems). His teaching approach leads with conceptual understanding and then deepens into formal analysis, which builds deep understanding rather than short-term memorization.
Mr. Saravanan fosters a classroom environment where students feel comfortable asking questions. He is notably patient and ensures comprehension before advancing to subsequent topics. During the week before the exam, Mr. Saravanan was reachable by phone or text and replied quickly to his doubts and questions , ensuring my son wasn’t kept waiting. This accessibility and responsiveness made a meaningful difference in my son’s confidence and readiness.
His ongoing feedback and willingness to revisit material from multiple perspectives reflect strong teaching judgment and a genuine commitment to student learning. This combination of clarity, accessibility, and academic rigor sets a high standard for instruction.
I offer my sincere appreciation for Mr. Saravanan’s dedication and recommend him with complete confidence.

Sir has great understanding of student requirements,
He understood my requirements perfectly to have more focus on problems and doubts related to that. He helps the student to analyze the problems to its roots to develop and understand solutions so that there is no confusion and need to remember long formulae. He is able to give clarity in concepts and has high patience in repeating the concepts until I understood them completely. He also gives tips and short tricks to help solve the problems faster.

Explains the concept in the way we understand and does it thoroughly.
Most of the teachers wouldn't like to repeat teaching a topic if we say we didn't understand properly . But Saravanan sir does not mind teaching repeatedly even if we forgot the topic.Physics can be understood just with definition and theory,sir takes all the efforts possible to make you understand the topic by drawing and explaining.
