Education - Curriculum - DIPS Schools

My son is a student in one of the DIPS school. I have tried to compare the curriculum of his to other students of same class in other schools. Here are some stats 4 Exam throughout the year; Overall Close to 20 lessons in Science, Maths and Social Science and about 35+ in English, Punjabi and Hindi; Main communication language is Hindi instead of Punjabi 😞😞 ; Other schools' curriculum have half of the study material in comparison ; Quality of study material is getting worst as years are passing. (Noticed a lesson in Geography which has one single line about Jozila pass, but excercise has a question about Jozila pass which needed to be answered in 6-7 sentences) Any other parents having their wards in DIPS schools do share your opinions too. I don't think (tried) communicating these concerns with school makes any difference
