Pick a topic
Choose one of the Scientific Studies topics above or type your own, then pick your state. WACE, VCE, HSC, QCE and SACE each word their questions differently, and the paper follows yours.
02
Attempt it yourself
Exam-style questions with the mark allocation showing, so you know how much to write. You answer them — nothing is handed to you.
A student tests whether music affects concentration by having ten friends complete a puzzle once in silence and once with music. Evaluate the design of this investigation and suggest two improvements. (7 marks)
