im not actually that sure like it depends ur raw marks might show that ur school marks really hard lik i know for my hsc results in english i knew my raw marks and my actualu hsc assement mark had jumped by 7 so my the difference between my raw and actual was +7 plus also i believe im not sure but if u beat ur assesment mark substantially they increase ur assesment mark so eg say u got raw marks of 70 for assesment and in the hsc exam u got 85 ur assesment marks might increase to 80+ so the method i used was to try and get the best in my hsc exams so my assesment mark could increase
