there is no prerequisites for INFS3070(orINFS3060orINFS3040orINFS3030),i'm thinking to choose one in the future,but i have never done infs1000 before,all of those units need assumed knowlodge infs1000 or equivalent, i was wondering is there a big connection between infs1000 and those units? would i be ok to study those units without complete infs1000?can anyone who has studied those before tell me whats in infs1000 and give me some suggestions?
