What is a TestOUT LabSim? How can I purchase a TestOut LabSim Voucher?
One of the MATC instructors posted a YouTube video with instructions. If you go to YouTube, search on MATC testout - it's the third video - PC Pro A+ LabSim Discount Pricing.
You could also check Blackboard to see if your instructor has posted anything about the product.
