IB and SAT stress

I’m a year 2 IB student who goes to a new IB school. I’m in the first graduating class and our school didn’t do a great job planning out our due dates for internal assessments and such. Now i’m left with a lot of work for IB which is all due before the ed deadline. I’m am at the top of my class and am a varsity athlete, but I’m afraid that I won’t have time to get my SAT score up with all the IB stuff I have to do.

Long story short: I have a 1300, straight A’s in IB classes, and lots of clubs and varsity sports. Will Vassar overlook my 1300 ed?
