<p>Hi, I understand changes can be made on test day. However, several sites do warn that this may not be the case; changes may be more likely available depending on the subject. Is there a higher chance W History to literature may not be as easy to make? </p>
<p>i guess you know the answer now, but i’ll still answer. Since they give you a booklet with all subject tests in it, you can just choose the one you want to do.</p>
