What are some differences between high school and college classes?

A few salient differences in the expectation level of a
college student are:

1.  In college, the student selects
and pays for his/her education.

2.  College is a not a
place where one would go to just, "hang out" or be counted.  Most of the college
students I have taught are serious students that attend college to achieve upward
mobility.

3.  Most college students attend college so that
they can obtain a career and receive a higher salary than a person that did not attend
college.

4.  The college staff seems to be more serious and
goal oriented.  Unlike high school, the atmosphere of a college classroom or library is
professional for the most part.

5.  Social interests such
as selecting a mate or a social group to belong to is also more plentiful and more
demanding than in high school.

6. Organization of time,
materials and ideas.  Most people live with family in high school and do not have to
concern themselves with rent, bills, gas, car payments and food.  In college students
are more responsible for themselves and their resources, so more life skills and social
skills are needed to tackle the "adult world".

7. 
Relationships both academic and personal are more intensified. It is not okay to tell a
friend or housemate that they can depend on you for something and then just decide you
will not keep your word.  In college, the stakes are higher and people teachers, staff,
friends and society see you as an adult that is responsible; so you must not overpromise
or under deliver.  It is good to balance your classes and your personal life and wait to
see if a person is trustworthy before you decide to share every detail about
yourself.
