If I am not mistaken some schools require at least stat or college algebra be taken? If its not well it is a requirement to receive an undergraduate degree.
I would not suggest skipping math AT ALL considering you will have to tackle that on the GRE. Also, other courses required such as Physics, Ecology, Genetics, Experimental Biology, Physiology, etc. will require a firm grasp on stats/mathematics considering chi-square analysis, ANOVA, ANCOVA, t-tests, fecundity schedules, energy calculations, physics are all common concepts in upper level bio classes. Not to mention physics. Did I say physics yet?
Yes, math is important regardless of whether or not a particular school requires it.
Since you have so many questions/doubts may I suggest you go to your advisor and talk to him/her?? Or are you still in HS? (just a question, not meaning to be rude)
