Combined English/Writing Score

I recently took the April ACT and got a 35C (35E, 34M, 35R, 34S). I did, however, get an 8 on the Essay, bringing down my English/Writing score to a 31. Do colleges (Stanford, Yale, Harvard, Columbia, Duke, etc.) use the English/Writing score, and if they do, should I retake? P.S. I plan to major in Biology or Religious Studies (with plans to become a doctor). Thanks!

Do not re-take for essay score. Work on the other parts of your application. You will plenty of opportunities to write essays.
