Students at City College of San Francisco are angry over the school's decision to cancel nearly all its summer classes. The community college is gutting its $4 million summer session to help close a budget shortfall that's expected to surpass $12 million. The move derails the plans of thousands of students who had hoped to make up missed courses or advance their education this summer. Many students are upset because City College previously cut hundreds of courses during the fall and spring semesters.
