The practice tests in this book are awesome. They really help in preparing my child for the upcoming exams. The standardized tests are usually harder and more complex than what is taught in schools. As it is, the teachers don’t usually prepare them specifically for the tests. Because of it, there is not much practice to prepare them for the actual test and the format of the test. I like the Lumos Learning books, especially the online version. They can give any child a boost and give them the necessary confidence for any grade. My child enjoys the online version very much. It is very easy to use and very practical. I highly recommend the books!
