Nowadays, learning online platform is entering the education system in the new era because you are able to learn from everywhere so, it helps saving your time and cost for sure. But in my opinion, online platform can only work for the beginner stage especially cooking and haircutting because there are a lot of details that if you would be a good chef and haircutter you have to learn on many small details that not be able to learn online class. So, I agree that learning cooking and haircutting online help save time and cost but I do not agree that possible to learn.
