Tutor.com offers affordable packages for your student, online, 24/7. I like that if he has a question he just heads over to the website, types it and has a teacher available to assist. And they cover a variety of subjects, including proofreading those reports before you send them into your teacher.
Many public libraries do offer Tutor.com for FREE. Stop your public library website for more information on details and times of availablity.
