What do colleges think if You have erratic grades?

<p>Hi,
I have two questions
what do colleges think if my grades spike up and down?, like A- and a C+ between semesters?
also
I only have a consistent good grade in chem
9th: 5 = B
10: 5+= B~B+
11: sem 1 6= A-
sem 2 6-= B+~A-
12: 7 unless i fail the exam= A+</p>

<p>and i 800’d the SAT chem.
however my grades range usually from the 5 to 6- range. B~A- range.
and my SAT scores are terrible for someone that outdo’s the ‘brightest’ kids in chemistry
