Will I learn ancient Hindi which is used in a religious book or normal day-to-day Hindi version used for conversation around India? And what is the difference between the two of them?
You will be learning how to communicate with people around India in Hindi i.e the day-to-day version. It is easier to learn as many of the words are replaced by English words which will make it easy to understand. Ancient Hindi words are not used much as they are not known now and also difficult to pronounce even for common Indian person and that is the reason they are replaced by easier words (Urdu or English words).
