Well, I think A300Capt said just about everything that needs to be said...
But I'll say a couple things anyway
. A poor grade in highschool, especially 9th grade, isn't really going to directly affect you for any post college hiring opportunities. Realistically, your grades in college are all that will matter in the end; however, where you will be able to go in college (at least, as a freshman)
does on your highschool grades
. More importantly, gaining study skills in highschool will be what you need to make it in college. Bad habits are easy to develop and hard to rid of, my roommate is the perfect example. Smart guy, but didn't let go of bad habits from highschool, I think he is failing all of his classes right now. $$$$$ ----> Drain
Anyway, if the grades are in the past, fine, don't worry about them; there is nothing you can do! Work hard for the future, and do not set your self up for disapointment in college by thinking that the trend can continue.
Sidenote: On financial aid, while it is true that many scholarships will be made possible by good grades in highschool,(and near impossible with poor grades), actual federal grants and guarenteed (subsidized/unsubsidized) stafford loans have absolutely no relation to your grades in highschool. Your grades in college may have a bearing on them, though. Just thought I should clear that up.
