Ritesh Khan Research scholar of Mathematics, Math lover

BEST possible guidance for LINEAR ALGEBRA,
Engineering Maths/University Maths(Pure & Applied both),
Real/Complex Analysis,
Abstract Algebra,

Now it's time to understand Mathematics and overcome the fear. It is not a so-called hard subject. If you practice it regularly and you have some clear cut concepts then this subject is no more difficult for you.
For this, firstly you have to change your mindset(viz. Some students think Mathematics is very tough. It is not for me. You're requested to change this type of mentality), none can change you unless you want to change yourself. Secondly, you need an excel tutor who can guide you properly. My role is just as a guide.


Each exam and course have different strategies. I will be teaching this subject from the basic level and then slowly move to a higher level. So that you have no more difficulties. There is a vast difference between Mathematics learning and problem solving for exam purposes. Mathematics is not a memorizing subject if anyone understands this subject thoroughly then he/she doesn't need to memorize formulae or problems.

Students must be serious and hard-working, don't need to be so-called 'Meritorious'. How I am teaching is totally different from the conventional method. I provide assignments, mock tests after each week and I always prefer to take surprise tests. I also help how to interpret a problem geometrically or what's the motivation behind it. It's more important to visualize a problem rather than solving it. So, If you want to master this subject then I am a suitable person who can help you. Also, please note that I teach not for money but to share my knowledge, and to improve my knowledge(It is not necessary that students will always learn from his/her teacher. Sometimes the converse is also true I think). In a nutshell, I enjoy teaching and feeling proud when I see my students' success.

I have been teaching for more than 6 years(offline and online both). As of now I have guided more than 40 students(online) from the US, UAE, Qatar, Canada, Netherlands, Germany, Singapore, UK, Australia, France, Saudi Arabia, S Korea, Turkey, China, Ghana, Kuwait, etc. This is a great experience for me. I prefer to teach using online whiteboard(Miro/Aww/Concept Board) where both of us can write real time on the same screen to understand the subject in an effective way and after the class I send the pdf of the class materials.

I also helped a lot of students (about 70) in their assignments. My broad areas of Research are NUMERICAL METHODS(Using MATLAB, Python), DIFFERENTIAL EQUATIONS, LINEAR ALGEBRA, NUMERICAL LINEAR ALGEBRA, CALCULUS, LAPLACE TRANSFORMATION, etc. So, I can easily help you on these topics as well as PURE Mathematics(like REAL ANALYSIS, METRIC SPACES, ABSTRACT ALGEBRA, COMPLEX ANALYSIS, TOPOLOGY, etc) I am also thankful to them for providing me with good & challenging assignments.

The followings are the few important topics/courses that I taught so far.
1. VII-XII Maths, IIT JEE(Main & Adv.)Maths, IB, CBSE, IGCSE, OLYMPIAD, BSc(Maths), NET(Maths), etc.
2. AP Calculus(all), Calculus 1,2,3,4.
3. Real Analysis(I, II & III), Metric Spaces, Topology, Algebra( Groups, Rings, Field), Functional Analysis, Linear Algebra(Eng.), Calculus, Differential Equations, Numerical Partial Differential Equations, Numerical Methods, MATLAB for Numerical Methods(University Level).
4. IIT Foundation Maths, GRE Math.
5. Advanced Differential Equations, Laplace Transformation, Numerical solutions of PDE(University Level).
Here are the few books which I usually follow
*CALCULUS by James Stewart & Thomas' CALCULUS
**ADVANCED CALCULUS(Geometric View) by J.J. Callahan
***LINEAR ALGEBRA by Sheldon Axler. \\ & Hoffman Kunze. \\ & S H Friedberg.
****NUMERICAL METHODS(MATLAB) by Steven C Chapra.\\ & Laurene V Fausett.


Currently, I am pursuing my Doctoral Degree(Ph.D.) in Mathematics(Applied) at the Indian Institute of Technology, Madras(IIT Chennai). I have a bright academic career till now and also qualified many competitive Exams like KVPY, JEE MAINS, WBJEE(West Bengal Joint Entrance Exam), IIT-JAM(MSc. Entrance in IITs)(AIR 240), GATE(AIR 67), NET(National Eligibility Test for Lecturership ) -JRF(AIR 9, AIR 50, AIR 65), etc. I was also an INSPIRE(DST)Fellow(SHE) in the period 2014-2019.

He is a Genius man! Linear Algebra

I am glad that I found Linear Algebra teacher like him in this site. I was astonished with his in-depth knowledge over the subject. For example, I was unable to figure out the section Diagonalization in Linear Algebra. I couldn’t recover a single word from book. But after doing his class it’s pretty much clear to me. Anyone can count his blindly. Happy to work with you sir!

Amazing Calculus 1,2 specialist and excellent teaching skill.

Mr. Khan is an amazing Calculus expert. He has the knowledge of any concept in depth. Initially, I was afraid of Calculus and was unable to figure out many topics. But Ritesh sir made it easier by giving real life examples and geometrical interpretations. Also he can explain a topic in different ways which makes him more attractive. Now I can handle the calculus on my own and the credit goes to him. Thank you so much sir for sharing your knowledge and spending your precious time with me.

A world class teacher of Calculus as well as Linear Algebra

I am writing this review after associated with sir for the past 6 months. {At the very first while I was searching for a Math tutor(Specially for Calculus & Linear Algebra) so many tutors were appear and I chose the first tutor available in the list & it was a blunder, that tutor was totally nonsense & I am sure that his degrees are also fake, just to attract student. Later I understood that the rank is not based upon quality this just based upon a premium membership.}

Somehow I found Mr. Ritesh in this site and asked for some trial classes. Anything what I am going to say will be less for him. I was astonished with his in-depth knowledge in Calculus and teaching methodology. His work is like an artist! Sometimes I feel myself lucky that he was my teacher. Thank you for everything.
