We got sick of other sites having so many resources and discussion forums but it took ages to find anything good. So we fixed that problem. You can filter what you're looking for by subject, school or type to help you quickly find what you're looking for.
You can also start your own discussion if you need a little help from the other Atomi users. This can be based on a specific subject question or just questions about the HSC in general. Also, if you're feeling generous you can upload and share your own resources so the other Atomi members can access them
