The last packet for Principles of Science, 9th grade, is probably school specific. Your best bet is to contact the school and have the teacher answer your questions directly. Most teachers provide a time during the day or after school to assist students who are interested in more help. Check to see if this is an option. You might also ask the teacher and the school counselor for a student study buddy; often good students volunteer to help or work for a nominal fee. This should give you a great start on getting your daughter the help that she needs.
