EdReady constantly updates your study path according to the latest information it has about your math or English knowledge. If you perform less well on some material, it is possible that your study path will expand and include additional units that had not previously been included. Similarly, if you perform better on some material, your study path may get shortened by some number of units.
EdReady will always try to present the most appropriate and efficient pathways to your target score based on the information available at that time. The more you use EdReady, the more accurate EdReady will be.
NOTE: If you think that your study path or progress is literally missing, you might be on the wrong EdReady site (check the URL in the address bar) or someone at your school altered your goal assignments. You can read more about the possible causes of (apparently) missing work.
