Not taking all the tests I signed up for.

I signed up for three SAT subject tests recently, but only had time to prepare for two of them. The test is tomorrow and I am wondering if I am able to just take two tests and skip the third test or will I have to take all the tests?
Does anyone have any experience with this matter?
Thank You.

You can two of them if you wish, but I believe you will not receive a refund for the one you already paid for and do not take.

Nothing will appear on your score report to indicate that you decided against taking a test.

Good luck tomorrow!

You don’t have to take all 3. I think you can even decide to take different ones then you signed up for. I don’t think u will be able to get a full refund for the one not taken.
