Younger brother...Helping my brother out...

<p>I'm not a parent but I would like some advice. I'm the oldest of four kids and you can say that I'm a father figure to my 13 year old brother. We all want our kids to be successful and acquire a college degree. What advice can you give me? How did you help your kids when it came to school or studying? How do you prepare a child for college? How do you get them interested in college? Study habits? Any advice would be appreciated. Thank you.</p>
