Hi Kyle,
Follow the stovebolters advise and you cant go wrong. I was a good student in highschool, but had a real hard time in college. It wasn't until my last couple of years that I learned the disciplin to realy make good use of my study time. A great professor told me that if you treat school like a job, that you will do well. I found that if you treat the school day like a work day, that you will have time left over at the end of the day to work on your truck when your grades get back up. I would get up and go to classes and labs and then before I could get distracted with TV and other stuff, I would just go the library and get my homework done while the class lecture was still fresh on my mind. Treat my school day like a 10 hour work day and you will be suprised how much you can get done. Sometimes it turnes into a 24 hour work day, but it all works out. Good luck and go hit the books.
