Serway/Faught College Physics, 7th edition
The site has information regarding physic classes. This site is only as good as the information is provides, it gives students the first step of the problem, but no additional assistance. It is also hard to locate necessary information within the site. The site does not have pop-up blocker set up which can be very distracting. This site was given to my 11th grade daughter for her AP Physics class and she finds it to be slow and not very helpful.
