What do the different sublevels, such as E, M, and H, signify in each nonfiction reading program?
In each nonfiction reading program, the passages are posted at three different sublevels of sentence complexity. For example, in the informational nonfiction reading program for 6th - 7th - 8th grades, the levels are classified into three sublevels of E (easy, 6th grade), M (medium, 7th grade), and H (hard, 8th grade), while the three sublevels in the expository nonfiction reading program for 9th - 10th grades are classified as E (easy, 9th grade); M (medium, 10th grade); and H (hard, 11th grade).
Since every standardized test includes various sublevels of sentence complexity, we strongly recommend you to read all the posted articles or passages regardless of their sublevels. But don't worry: even the hardest passages won't be too difficult to tackle, thanks to the tutorial sections attached to each one.
