choosing a major problem

Hello everyone I’m a junior in NYS. I want to study wildlife Biology at UAF however i was a super bad student and i failed biology in 9th grade with a 27 ( i didn’t care about school then) however in 10th grade i got 80’s throughout the year and got a 92 on my NYS living environment regents. I’m now taking Ecology and earth science i have 90’s in ecology and high 80’s in earth science, i’ve preformed really well in 10th and so far in 11th i’m doing even better, I will take AP Bio for my senior year. However heres my issue; when applying should i remain undecided instead of picking the major that way they admission officers won’t just look for how I did in sciences. (I know this has been vague but any help or guidance is much appreciated thanks!!)

Well it looks like your grades are improving. Are they markedly better in non-science areas?

well yes i have very high social studies grades and a 100 average in CC Algebra B (failed that in 9th and then they made it a two year course) my lowest grade is an 87 and i haven’t scored below 90 in any of my state regents or common core tests so far. my overall average for the 2nd marking period was 92, it was 85 in the 1st quarter. (Do colleges factor in improvement?)
