In this era of globalization, a person gets a chance to interact with people living under different circumstances. In order to avail better international jobs and learn about other cultures, a person needs to learn the skills of dealing with differing viewpoints and interests. By registering students, who are studying different subjects or having varying hobbies, in same school they can be familiarized and adopted to the real picture of this world. However, in my opinion, during higher studies the pupils of same interests should be admitted in a same university so that they can solely focus on one area.
When a school gives admission to the students having same subjects and nature, then usually less disputes raise among them. That results in a more disciplined class environment. By exploring the same domain and discussing ideas with each other, the pupils can learn faster and with ease. They will be able to acquire and grasp knowledge at the same scale that can help the schools to maintain their average success rate. Moreover, if all class fellows will be studying medical, in order to pursue their career as doctors, then from very early stage they will learn to compete with each other. They will become more enthusiastic and proactive. Additionally, these school time relationships will last with them forever.
On the other hand, when students from different families and of various attitudes come up together, then they learn to listen and understand the differing thoughts. Their perspectives can vary that will help their school mates. They will get a chance to share cross domain information and add to the general knowledge of each other. In addition to this, when they will enter into the practical world, then they will have to work with people having experties in different fields of life and employed to other departments within same office. The possibility of training the pupils from the beginning will help them in long term.
I personally believe that during school life the children should study in same school regardless of their main course of Arts or Science, as then they will be able to build their social skills. Moreover, at primary level, the course books are very basic and its good to share the concepts. However, at university level, all pupils of same branch like medical or engineering should be enrolled together so that they can focus on their own subject of interest and share real world experiences.
To conclude, the concept of enrolling students of same or different preferences together is debatable, as each one of these methodologies has its own pros and cons. Thus a person should be given a chance to experience both by educating them together during school life while splitting them to different universities for graduation. This way, they will gradually develop their social skills and professional experties.
