YEAR 12 These clever VCE Study Packs will provide you with key information you need to know to help ensure VCE success ...if you have the information, the rest is up to you. Study Packs make it easier ...because each card highlights key points that will help you learn and memorise what's important. The design is simple so that you can carry the cards in your pocket. This means you can swot in the bus or the car, or take a quick look before lessons or even when on holidays. Features: *Written by key subject authors and course experts *All relevant knowledge and skill objectives are covered *Topics are clearly identified on each card *Examples and diagrams are used to assist understanding *Each card is numbered for easy reference *Dot point format make it easy to memorise key information
