What Should an 8th Grader Know for the SSAT?

So, my daughter is going to be taking the SSAT in few days, and she’s a bit overwhelmed by the amount of content on the SSAT, as some of the content hasn’t been taught in school yet. (for some reason) What do you guys have to say? Should she stress on the topics?

As well, what books are you using? How difficult did you find the exam?

Remind her that 9th and 10th gradees take the exam, too. That is why some of the material is more advanced, but that she will only be compared to other 8th graders. She isn’t expected to have covered it all already!

The practice tests and exercises on SSAT.org were pretty helpful, btw.
