Jacaranda Physics VCE Units 3 and 4

Everything your students need to succeed.

The best Physics series for the new VCE Study Design. Developed by expert Victorian teachers for, VCE students.

Get exam ready: past VCAA exam questions (all since 2013)

Students can start preparing from lesson one, with past VCAA exam questions embedded in every lesson.  Practice, customisable SACs available for all Units to build student competence and confidence.

Learn online with Australia’s most powerful learning platform, learnON

Be confident your students can get unstuck and progress, in class or at home. For every question online they receive immediate feedback. Teacher-led videos to learn and re-learn. Instant reports make tracking progress simple.

Combine units flexibly with the Jacaranda Supercourse

An Australian first, build the course you’ve always wanted with the Jacaranda Supercourse. You can combine Units 1 – 4 in one title, so students can move backwards and forwards freely. Or Junior and Senior Sciences for when students who need remediation, extension or acceleration.
