Hi,
For learning purposes the best choice is to invest 200$ per year for a vmug advantage single subscription. That's not free and yes, a year might be a short time. "Free" per definition includes the latest greatest version - that's a common endor rule.
I've reposted this info quite a few times, sorry for this. But, purchasing a bundle for each member in a company team includes tremendous advantages!
That said, have a look particularly to the very attractive offering content.
