Welcome to a comprehensive updated set of resources for ATAR Chem. My name is Andrew Weng. I used to work as a medical laboratory scientist before discovering my love of teaching. Since then I've added a few more letters after my name (BAppSc, BEd, MEd) and spent most my time teaching IB Chemisty overseas in international schools. Now that I'm back in Australia I've been focussing my efforts on QCE ATAR. I hope you enjoy!
