New version updated
There was an issue with the exam simulator functionality,thankfully it was fixed with the new version release.
Response from developer
Hi Alejandro, thanks for flagging this — you were right, there was a bug in v1.0 that prevented the Exam Simulator from advancing past question 1. It's fixed in v2.1, which is now live on the App Store. We also added a NAC Circuit Calculator, SLC Loop Resistance Calculator, and NFPA 72 reference cards in this release. Email us at arun@voltexam.com if anything else comes up — we read every message. — Team VoltExam
