The HSPT and ISEE math portions of the test cover rudimentary math skills. However, as we all know well if these skills are not taken for a test drive on a regular basis it's easy for them to get rusty. Fifteen minutes a day of practice is good enough. But the earlier you start, the better. Go to our "Members Only" section of the website and read the document titled "Math Skills Overview" which outlines the basic skills that students need to have to perform well on the test.
