Abandon relic quest and get it for other class

Hi, i have a schoolar with in some part of relic quest, I would like to start the relic quest for other class, all the advance that i made on relic quest is lost for SCH? Example

SCH= I need to kill Garuda for relic quest
Abandon quest
BRD= I go Bard, do the relic quest.

Then if i want to continue with SCH relic quest, i need to start for the beginning? or i continue from garuda?

Progress is lost if you abandon it. You need to start back at the beginning of the SCH quest
