Why do you need a program for the core test? You should have the info memorized and it is a multiple guess test.
Look for the best fit and don't stress on the details.
You will do fine, OK?

Know your line and point source calcs, decay calcs, and how to use/read a chart of the nuclides. The rest is theory and practice.
GOOD LUCK ON THE TEST. You will do well, just don't freeze and go blank.
