IB Astrophysics Option
Below is an astrophysics test from 2012. Try the problems and click on the "video solutions" buttons to check your answers. There is not a solution video for question E1 C. There are two video for each practice problems so that you can hear it explained differently if you choose to watch both. If you would like to print out the test, click on the "copy of test" button at the bottom of the page.
