Learning of languages is similar to sports. The brain has to be exercised constantly. Frequent repetition works better than rote learning. With rote learning, 75% of the material is already forgotten after two days. Repetition can prevent this.
When studying languages overseas, retaining information is assured and the memory-loss curve practically stays at the zero mark, because what you have learned can be applied immediately. This is the reason why studying a language in a country in which it is used locally is ten times more effective than taking courses at home. The key to success is systematic repetition of the studied material.
