Briefly,college life differs from high school life in three ways.
First,in middle school,we did not live on campus,but at college,we have to live on it .Next,in high school our teachers showed us how to solve every problem.At college,however,we are left to solve problems by ourselves.Finally,since we didn't live on campus in high school,it was usually easy to keep a friendly relationship with our classmates.Yet,at college.As we live and study together,there is bound to be divergence or disagreement in opinions,life styles,etc.So we have to learn to get on well with each other.
Although I often recall my high school,I like college life more.
