http://passyourclass.com/products_DANTES.htm#d_statistics I'm studing for stats and not doing very great... do you think this is worth buying?
These books (assuming they're the same) were great value when you could get them on eBay for around $7-9 a few years back. They didn't have a guarantee, but for the price they were adequate. What they're charging now is ridiculous. Instantcert is definitely a better deal.
