Careless Mistakes

<p>When Saturday rolls around, how can I be sure that I don't make the careless mistakes that I'm making on the practice tests I've taken? On Math sections I've gotten a #1, #4 wrong..etc. because I didn't fully read the answer choice I was selecting and chose "4x + 6y" instead of "4y + 6x"...these careless mistakes can hurt me a lot so what are some tips on preventing it.</p>
