total of four batches of students make their way to the campus every year, staying for up to two months. Priority is given to scholars of HCI's Bicultural Studies Programme and Humanities Programme. Students in the campus take lessons together with students from China in partner schools, carry out community involvement activities, and take field trips to cities such as Xi'an, Tianjin and Shanghai. HCI has been quoted as saying that it is looking to opening satellite campuses in India and the United States, with the aim of establishing the two in the near future. In July 2010, it was announced that HCI would be developing a school in the Sino-Singapore Guangzhou Knowledge City in Guangzhou, akin to that of its first satellite campus, following the inking of a memorandum of understanding. This would see HCI partnering a top local school for exchange and mutual learning programmes. Xi'an Winter Campus In addition to the Beijing Satellite Campus, the Xi'an Winter Campus was set up in 2011 with its site based in High School Affiliated to Xi'an Jiaotong University. Students partaking in the Winter Campus programme would spend four weeks there attending lessons that are conducted in Chinese and focused on humanities subjects including history, geography, literature, socio-Economic as well as political aspects of China. This programme also provides opportunities for students who are strong in English, mathematics and the sciences, but weaker in Chinese, to better master the language and to immerse themselves in a different environment, and at the same time, appreciate Chinese culture and history. Information Secondary 1 (around age 13) boys first enter the High School Section and study there for four years before proceeding to the College Section, where they prepare to take the Singapore-Cambridge GCE Advanced Level examinations at the end of Year 6. The High School Section uses the Mean Subject Grade (MSG) grading system in tests and exams. The school-wide Integrated Programme offered enables students to skip the Singapore-Cambridge GCE Ordinary Level examinations, which is typically taken by Secondary 4 students in Singapore. The Hwa Chong Diploma was introduced in 2008 and is awarded to the best performing 30% of its graduating cohort. It is awarded on top of the GCE Advanced Level certificate, and is an added qualification to university applications. The school enrols an estimated 4,000 students, spread across the six levels, with a student-teacher ratio of 13:1. Hwa Chong Institution
