always thought it would be great to have all edu materials in one place, not like I need to go and check different sources. WIth this company I found that, their packages are complete and contain al lthat is needed, whehter it is psycholgy aspects, or technican Andrew fundamental aspects, or even back testing techniques...all I get here. Yet, would be nice to have lower prices
