Hello,
I would like to help you with the concepts regarding "Electricity and Magnetism" as you can look over my profile and get to know about my background in Physics, Chemistry, and Mathematics. Being a candidate for one of the toughest exams IIT-JEE helped me to learn and apply it well in problems to crack the sums as well achieving a milestone of clearing the exam and getting into IIT.
So, you can trust me well regarding the concepts.
Also, I am new here as you. So, nothing to show off regarding my profile and etc on freelancer but I can assure you that you won't regret. If you feel that I can be of help to you, then kindly contact me.
