Should I retake the Math II Subject Test?

Hi I’m a rising junior and took have taken the Math Level II subject test twice already. The first time (May), I did no studying whatsoever as this was the first standardized test I had ever taken, and I didn’t really have any upperclassmen to ask because they were also going to be taking the same test for the first time (I’m in a math class that would typically be for the grade above). So I got a 710 on my first try, and I really wasn’t aware of how fast you had to move.

Then I took it a second time in June, right before finals, instead of the World History one because juniors had been telling me that they regretted it. So a lot of the people in my class ended up switching tests last minute, as I did. On that one I scored a 750.

I have no SAT score or ACT score yet as I plan to take it this upcoming year. I’m also planning on taking the Biology SAT subject test (both E & M; you can take both on the same day, right?) & U.S. history in June. Then senior year I might take the English SAT subject test. So my question is, should I retake my math level II test again? I really want to get into an Ivy League school (Stanford’s both my #1 choice and my reach school) and honestly I would settle for any Ivy League. I know that some colleges do require you to send in all SAT subject scores, so I’m hesitant on taking it a third time because even though I did take the first one as a sophomore with no experience and studying, I doubt that the colleges are actually going to know that or care.

I’m an international student w/ a GPA of 3.98 (no honors in my school, and although we do have AP classes, we only get the honors GPA boost not the actual AP one). I’m involved in varsity track & XC, NHS, and am one of the leaders for the Animal Advocates club at my school. As of right now, I think I’m in line to be captain for XC and the main leader for the Animal Advocates club my senior year. I also know that colleges are also concerned about essays as that’s how they get to learn about you, and I already have an idea about something that I would like to write strongly about that explains how I grew up to be the person I am today and what I’ve learned.

Wow…I’m not even halfway through summer and I’m already feeling the stress of it all. Please help!

I wouldn’t take it a third time. That might look “greedy.”
