Should I retake the ACT?

<p>I took it in April for the first time and got a 31. 35 English, 28 Math, 29 Reading, 30 Science, 8 Writing. The field I'm most interested in right now is engineering, so would taking the test again to hopefully raise my math and science scores a point or two be worth it? I'm also not 100% satisfied with my writing score. </p>
