I definitely recommend studying and retaking that - seems like the easiest one to pull up. My son got a 27 his first time on the English, a 31 on his second attempt and a 35 on his third try! He did study between them - not a whole lot, but just worked through that section on all the sample tests of the book he had. This increased his composite from a 31 to a 35, which I also think makes a big difference. All his other scores stayed the same or increased slightly each test (just from knowing what to expect and being less worried I think)!
