Without the family support and guidance they were used to, decisions they make do not always reflect their best interest. Some weather this storm, others do not. Students who elect to attend a two year institution have time for transition from high school to adulthood in a friendly environment with support from family and friends near at hand. They aren't faced with as many distractions and are more focused on the task of learning. The emphasis of the school itself is geared more to academics than social aspects which help keep the students focused.
Classes are smaller and more personalized.
Instructors know their students and work with them on a more personal level. There are less instances of academic probation among students in a two year college setting. It is a more student friendly atmosphere. Cost is another major factor to consider when choosing a college. The cost of two years at a Technical College is probably less than the cost of one semester at a 4 year college or university.
