Thanks for the review @rosatravels, As I said in the reply for of your review in the previous post, I bought a new mic for making videos but didn't configured it correctly, hence the echo but now I think I did it correctly this time

Also, I am trying to speak slowly but it's tough, I tend to pause again and again while speaking so I have to edit it

And btw, can you please explain me how can I make the tutorials more structural?
