The following is an unedited tip from one successful CA PI test taker to the next applicant who will be tested soon:
My recommendation to other candidates is to make full use of the
"mark"
option as you go through the test on the first run through.
Mark the ones
that you'd like more time with as you go through the
test, but leave nothing
unanswered. Then when you're done, you can
choose an option to view all the
marked answers at once and ponder
them at your leisure without the fear of
leaving anything blank due to not finishing the test.
