Taking three sat subjects tests?

Hi, I am a junior and I plan to take sat bio and sat math2c in May.
I am currently taking ap bio and precal, but it’s getting harder even with coming ap teats.
I had 760 on sat World history and now I have a second thought of not taking sat bio and focusing on math2c.
I have no athlete and music talents so I try to best to do on SAT tests.
My question is, is it ok to give up on sat bio and take only math2c?
Or try harder to take both in May?

Any comment would be welcomed
Thank you

The answer to your question partly depends on colleges to which you intend to apply and choice of major. The majority of colleges do not even use subject tests for admission. Most of the ones that do are among higher ranks but for all those colleges you only need two, except for Georgetown which stands alone among all colleges as recommending three. In other words, if you are not applying to Georgetown, you really only need at most two good SAT scores.

As to major, you have a different issue. Though you still only need two, a number of colleges that require or recommend subject tests want to see one in math and one in science if you intend to major in engineering or possibly science. And thus the history test may provide little for determining admission for those majors, and you really need that math and also a science. If your intended major is not engineering or science, a high math 2 score would be the best addition to your history test.

Sure. A subject test wont be a make or break for your application.

The answer also depends on what kind of colleges you’re aiming for, and what your current background is like.
