For all of the NTS renewals I've done over the last couple of (gasp) years, I have yet to subscribe to the professional literature access offered by NASBA. I've paid enough $$ in exam fees that they should give me a lifetime subscription.
If you have a good study package, this is probably just a distraction, but it could interesting to mess around with and it's yours free for six months if you have an NTS.
Get the subscription here from NASBA.
A description from cpa-exam.org:
“CPA exam candidates can get a free six-month subscription to professional literature used in the computerized CPA Examination. This online package includes AICPA Professional Standards, FASB Current Text, and FASB Original Pronouncements. Only candidates who have applied to take the CPA exam, and have been deemed eligible by state boards of accountancy, will receive access to this package of professional literature.”
