7-680 Practice Exams?

ChimeraXXL

Work got me the online training course through learning.microsoft.com

It was kind of a letdown for the cost. Are there any free practice tests? The tests I've found so far want to charge me around $100 dollars and budgets are looking abyssimal. Does anyone know of any practice exams that will be of help? So far i've been reviewing the material here, and redoing the e-sim labs, but there's still questions in the practice test that were never touched upon in any of the material we got from microsoft.
