students over the age of 22 who pursue higher education. Students may apply to many institutions using the Common Application. Fees are generally charged for each application but can be waived based on financial need. Students apply to one or more colleges by submitting an application which each college evaluates using its own criteria. The college then decides whether or not to extend an offer of admission (and possibly financial aid) to the student. The majority of colleges admit students to the college as a whole, and not to a particular academic major, although this may not be the case in some specialized programs such as engineering and architecture. Common criteria include ACT or SAT scores, extracurricular activities, GPA, demonstrated integrity, and an application essay. Further criteria, used to varying degrees, include athletic ability, interest the student demonstrates in the college, legacy preferences (family members having attended the school), race, ability to pay full tuition, potential to donate money to the school (development case), desired class composition, perceived fit, subjective evaluation of student character (based on essays or interviews), and general discretion by the admissions office. The importance of these factors varies between universities, and selectiveness varies significantly, as measured by admissions rate. The admissions rate can range from 100% (schools that accept everyone with a high school diploma) to under 10%. Vietnam In Vietnam, most students apply to study in four-year colleges, universities, or academies after completing high school. Others apply to two- or three-year colleges, where they have options to transfer to a university once earned their degree, or to vocational schools. While the number of students applying to two- or three-year colleges and vocational colleges are increasing, especially the latter in recent years thanks to government's efforts, the number is still insignificant. Preparation for college and university admissions usually do not begin until the last year of high school. Students will usually attend university fairs and career counselling sessions, organised jointly by Ho Chi Minh Communist Youth League and local governments. Representatives from both national and local colleges and universities will travel in troupe to organise booth and answer questions from students. These activities are in session throughout the school year, though different locales have different day when these activities are organised. This usually means that students in provinces most distant from major educational centres, such as Ho Chi Minh City and Hanoi, will attend these fairs
