Hi @SabihuddinAhmadSiddiqui and welcome to Esri Community! Because the body of your message is primarily a question about watching Esri training videos, I've moved this post from our Member Introductions Board to our Esri Training Questions Board where it's more likely to be seen and responded to by members with relevant expertise. Please feel encouraged to (1) update the title of your post to more closely describe the help you're looking for, and (2) publish another introduction post that's about yourself in our Member Introductions area so that your GIS peers from around the world can learn more about you. All the best!
