<p>I have till October 10th to register for November testing and won't get my results from today till maybe next Sunday at best. I feel pretty confident on the tests today but don't know how it will turn out. My plan was to register for them and not show up/cancel if I do good enough. Is that a good plan or have undesired consequences?</p>
<p>That’s a good plan if you really want to get good grades on your SATIIs. The only downside though is that you might be wasting money.</p>
<p>Definitely register! If you don’t and then feel you need to, you would go standby. But that would be very stressful! No one needs that. Pay for only one subject test, then add on a subject test if you need to on testing day, and SAT will bill you.</p>
