One B Freshman year of high school?

<p>I got a B (89 but my school only counts semester grades) for Alg 1.
I got all A's in my other classes (including Honors English and Honors Physics).
I am also taking all honors classes for my Sophomore year.
I took 2 AP tests (US History and US Government) during my 9th grade, but I haven't
got the results back yet. I've also competed at the State level for my Science Fair,
and I also participated in the State FLL robotics competition in my middle school years.
Anyways, how much do colleges take into account your freshman year grades?
Are they a important factor because of GPA? I would just like to hear your opinions on the topic.</p>
