More than 850 HSC students from all over NSW are  on campus this week for the annual HSC Booster Days.  The popular long-running event offers Year 12 students revision tips and extension opportunities for HSC subjects, including mathematics, science, business, economics and law, through a combination of hands-on activities, and specialist lessons provided by HSC specialists. Anecdotal feedback from previous years indicate that students gain fresh perspectives and in-depth understanding of concepts previously discussed in the classroom. Sessions are run by UNE academics and PhD students, as well as specialist HSC markers.
