At the comment section of each lesson of the on-demand online course, I will only answer questions directly related to the topics covered in the corresponding lesson of that course.
For questions not directly related to the courses you signed up for, I will try to be helpful. You can email me with your questions.
For questions that are easy and quick to answer, or problems easy and quick to provide solutions for, I will generally help you.
For questions or problems that take substantial amount of time and efforts to respond, I would suggest you to contact me to arrange the paid service of either 1-on-1 Excel training/tutoring or Excel consulting.
If you are not sure, I do encourage you to contact me. Most of the times you will be pleasantly surprised with the help you get from me. I will always reply to let you know what I think about it.
