How long will it take to learn English well?
Firstly, learning is a continuous process. We may not define this by the duration in hours/months as well. Instead, it is up to the ability, interest, involvement, and potential of the learners. We cannot classify the average or bright learning personality. Anyhow, it will probably take a minimum of two months to acquire the lingual skills. The amount of time we spend on educating ourselves, the amount of efficiency will improve the counterbalance to the efforts. It's entirely based on the needs that have arisen for us and the way of utilizing the opportunity wisely.
