You can directly access your account by going to http://app.homeschoolboss.com/ . Then you will click the Map Testing box in the upper left hand corner. That will give you a list of the tests scheduled. If you hover to the right of the test, you will see a Manage Test pop up. Click that and you will be able to choose to add either the Language or Science Tests. Those options are located beneath the boxes containing the student information. You will then be asked to pick dates and you will proceed as you did when scheduling your original test dates.
