For a long time, I had spent a great amount of time to learn grammar, structure and vocabulary as well as collocations etc..Since I am kind of slow in memmorizing stuffs like that, I had been thinking about ways to learn faster. I watched every youtube video about how to and jumped to a conclusion: listening. I had heard about it dozen times bit it was this time did I understand deeply about its huge benefits. What's more, a few days after my discovery, Mr Jonathan, an Italkier advised me the exactly same thing. I truly hope it will work.
