The same courses that are $640 for a three month subsrciption through Johns Hopkins CTY are currently between $35 and $50 or so for a year subscription through the homeschoolbuyerscoop.
http://www.homeschoolbuyersco-op.org/ And there is no prerequisite (CTY requires a qualifying math score and completion of at least grade 5 math. FYI, DS7 just listened to the first earth and space science lecture, did the activity and took the first assessment with no problem. He's about done with third grade EPGY math, but there were no math questions on anything covered so far.)
The group buy ends tomorrow, May 28 at 11:59 p.m. so if you're interested, you need to sign up today or tomorrow.
