Are there any subjects that you think schools should add to their curriculum?

Thanks for the question! 

Science is continuously evolving, so is business and Arts. Adding subject to the curriculum is depends on the context of the culture. 

Subject which will add value to the area of knowledge should be emphasized. Moreover the subject that make student more loyal , polite and increase their level of Integrity should added in the curriculum. 

Nay, I feel usually everything is prepared well and smart
