Various points to prove the fact that the school system curbs individual talents are:
Focuses more on memorizing facts and data rather than encouraging them to understand concepts and ideas. Thrust on taking exams rather than focusing on increasing the mental and intellectual aptitude of a student; The irregular student-teacher ratio makes it impossible for the teachers to provide individual attention to each and every student.
One-to-one interaction with the kids has lessened these days.
Time bound classes or specific syllabus does not encourage out of the box learning.
Quantity matters more than quality.
