<p>I have Bio and USH SAT subject tests tomorrow, but I feel that I am not ready for the Bio test… Can I just take US History?</p>
<p>If I can, do I just do USH and leave, or is there anything I have to fill out (ex. explaining why I didn’t take bio)?</p>
<p>I have the EXACT same question and need to know as well!</p>
<p>Yes you can take only one, as long as you don;t start the second one. You just loose the fee.</p>
<p>If you take the second you can not cancel without both scores being cancelled.</p>
<p>So as long as I don’t start on the second one, I should be fine right?</p>
<p>So do I have to tell the proctor and leave after I finish my first test?</p>
<p>Yes, you should tell the proctor so the proctor doesn’t go looking for you.</p>
