<p>I skipped one of the first bubbles on a first reading section of the October SAT and continued answering questions. Halfway through the section I realized what I had done and I erased the bad answers and filled in the right ones (or those I thought were right). Is there any chance at all that I didn't erase well enough (I remember telling myself I'd need to go back and re-erase some, but I never got the chance) and that it affected my score? How "completely" do you need to erase so that the machine understands your answer? If I were to get the test hand scored could it help? I was thinking I'd order the Question and Answer service first, to see if a lot of the the mistakes were early on in the first reading section. Is there any other way to find out which questions I got wrong? Is it even worth it??</p>
<p>Thanks</p>
