@Calliemomofgirls, here is another thought. If the December scores are not where you need them to be (and your kid is not burned out of testing yet) you may consider scheduling a flex test in early January. The results will be out in time for submissions. The difference is that your kid will take the test by herself rather than in a group setting, and may feel more comfortable and less stressed as a result. Search for educational consultants in your area that are certified to administer Flex SSAT. It will cost a couple of hundred though. Again, just a thought.
Edited to add: You can schedule Flex tests on any date that works for you and the consultant. You don’t need to do it on one of the official SSAT testing dates.
