I know one prep company offering free SAT resources online. TestprepKart is probably the best, if only because it uses official SAT material. This is a great place to start. If you find that an online program doesn't help you reach your score goals, follow it by working with an established expert tutor or test prep professional. Even the highest achievers rely on coaches to help them.And for further assistance you can mail them at info@testprepkart.com.
