Don't be afraid to post your question on the PCS Forums as well. There is nothing in the exam that says you can't ask for help. It's open book and "use your resources" after all.

You can also call Bob Dodds and get specific questions answered at any time.
The exam is not meant to stump you - it's meant to test your clubmaking ability.
