This is the idea of integrated pre school offering.The child is given training & education according to his/her interest area.The child is classified in different categories & accordingly he/she is given a training.
Why this idea?
Because in home, a child is generally asked to do a home-work,which is related to a syllabus of school,nobody gives attention to his/her interest area because of so much of competition in school to get good marks.
Hence this is the best idea to excel a child in his/her interest area.
