Registering for Multiple SAT IIs but Taking Fewer?

I registered for the Math L2 and Bio SAT IIs a while ago for May, but I’m having doubts about whether I’ll be prepared enough to take the Bio test. If I take the Math L2 but not the Bio test in May, will a score still show up for the Bio test?

How would there be a score if you didn’t take the test? You can take a different subject test that day instead of bio. When you take the test, you get a booklet with every subject test and you can decide which ones you want to take then. You can also add a third test and they bill you afterwards. It must say on their website how refunds for untaken tests work.

Correct. If you don’t bubble the code for the bio subject test, no score will be reported.
