I have just finished the tech cert & we started cross referencing before christmas. Our assessor has cross referenced all but 2 of the knowledge in unit 302 and all but 6 in 306
Lots of other things cross referenced to the knowledge of the compulsory units only really looked at cross ref for optionals 306/307/308 as a group. Also Cross ref a lot of criteria for 306 too
looking at the criteria of the optional units I have chosen more will be cross refed when we get back
