Can I get into SUNY Oswego or canisius college

I am a junior in highschool and I’m looking to apply to SUNY Oswego, and canisius college. However my first average was a 76% and my second about a 81%. I know they are not very good grades but I’m trying to bring it up to at least a 87%. Will that better my chances to get into these schools? I am cocaptin of the swim team at my school and I was on the tennis team, I also take a college class on Saturdays that will give me about 12 college credits. I am also a intern at my local hospital. I also will be going to Puerto Rico for a 12 day veterinarian program. I am also trying to volunteer at my neatest aquarium or animal hospital.Will all that and a good SAT score help me get in ? Mainly Oswego that’s my first choice canisius my second.
