Senoir High School schedule?-taking a math?

Okay by the end of this week i have to decide on courses i am taking for my senior year in high school. I have been told many times that you NEED. not that you should take a math cl senior year. but here the thing im really bad at math and i could take a cl next year but all i would be doing is hurting myself b/c i prob wouldnt do well in that cl. I have manged to have an 85 in algebra 2 but that b/c i have to work my off and stay after all the time. It not like im not taking other good quality courses. and im taking English honors as well as other academic cles in everything expect math but people are saying i need a fourth year of math to get into a 4 year college. Which is what i want to do. So yeah my question is is it really necessary to take a math senior year? i know of 2 girls that got into a four year college and didn't take a math. one went to private and the other went to public school. can not taking a math really not get me into college?
