Wall Street is not bad, but it is the favorite adult oral training institution for young people now, not for school exams. For those who want to go abroad, work in a foreign company, or speak standard and fluent English, I personally think it is worth it. I also know some Global American English. A friend of mine has a class there, and his oral English has been very good for half a year. Universal Midland is a teaching model similar to Wall Street. But many people say that the cost performance of Global America is higher than that of Wall Street. If you like the teaching method of this training institution, you can choose Global America. If you don't feel at ease, you should visit both places, listen to the experience class, get to know more, and make a comparison. You should get the answer soon.
