Bad first semester grade sopre year?

I am usually a solid A or B+ student in all my other academics but math is my weakest subject. Freshman year (algebra I), I got solid C+'s and one B-. I got a D+ on both the midterm and final, but semester grade was a D. This year (sopre year) I've taken on 3 honors cles and my work load is increasingly heavier. For 1st quarter Geometry, I got a D+ and 2nd quarter I got a solid C (74%) and failed the midterm O_o. My semester grade was not good. I switched to a different cl to avoid failing the cl 3rd and 4th quarter + the final. I was wondering if my chances at a good college (preferably state, etc) are butchered? I know this will be on my transcript and I've been worrying like crazy. Please give me your opinions on whether or not I have ruined my chances at being accepted into a college?
