Mounts and training question

I found some information saying patch 2.4.3 lowered the required level for Apprentice Riding from 40 to 30 and the cost from 40g to 30g. Since this is patch 2.4.3 is Apprentice Riding available at level 30 or 40? Also, what is the cost? (not including rep discounts)

yes on ptr, its lvl 30 for the first mount

Thank you :)
