Hi,
I am pleased to see your project.
I am an electronic engineer by profession and have been tutoring online for the last 6 years. i am running my online tuition academy with the name of StudyIn.
The best thing which I offer is a trail session which is totally free of cost. I have different GUI's to demonstrate different techniques and graphical representation of the subject.
Functions, domain/range, limits, and all that is included in calculus.
I can provide you the details of my ex-students which can share you their experience with me.
Kindly respond earliest so that I can schedule your free trail session.
Best Regards
Hasnaat Ahmed
