SAT II- math and science??

<p>So I'm thinking about doing something in relation to engineering in college, and I see that most colleges either require or recommend taking the sat subject test for 1 math and 1 science. I know I'm going to take the math 2 test, but i don't know which science test to take! I'm in physics this year, but honestly, I don;t understand a thing that we're learning, so I wouldn't want to take the test for that. I have taken biology and chemistry but I've pretty much forgotten a lot of the stuff that I've learned, so I'm not sure if I want to take the test for that. </p>

<p>I think the easiest test for me would be math 2, US history, and Chinese, but I just have a problem about the engineering needing science. But then again, Im not completely sure that I want to go into engineering, but I want to have the option open. </p>

<p>So do you guys have any suggestions on which test I should take? Biology and have a hard time reviewing/going over the stuff? or just take the US History since im already gonna take the AP exam for us history this year?</p>
