What is your plan for success as you move closer to your high school graduation?

actually my high school final exams are starting this wednesday, and i need to get really good grades to get into the college i want and to do the course i want. i'm a really ambitious person, but also lazy at the same time, which is a really bad combo. i'm into science so a course in college that involves that is what i really want. but turns out, i didn't do anything for the year and now i'm cramming as hard as i can, otherwise i'll just have to repeat. well, that's my experience now, i don't know what kind of answers you're looking for...sorry :)
