Just my opinion, but: I'm not convinced that being concerned about college admissions is productive now, at least not for me. My kids are all very young, and the admissions process could be very different when my kids (aged 5 - 9) are ready to apply to college.
We're going to encourage DS9 to take a couple of years between high school and serious college. He's going to graduate two years early and we'll encourage him to explore different subjects at one of the local community colleges, get a part-time job, enroll in internship programs, take up a serious hobby...whatever strikes his fancy for the most part. Well. We probably wouldn't be happy with "Think I'll surf the web 'til I'm 18."
The idea behind all this is to give him a huge gift of time to explore the world and his interests when he won't have many other responsibilities. If it works out, DS7 and DD5 will hopefully have exploring time as well.
