research topics

Topic I am considering..

1. "Does striving to make it into college make students work harder in High School? What is the correlation between student high achievement in high school and how well those same students do in college?"
2. "Is going to a private University worth the additional cost compared to a public University or Community college?"
3. "Does class attendance really matter? Should students in college be graded on whether they attend class?"

I want to create an analytical research paper.
