This app didn’t just lock me out, it completely hijacked my phone like malware for hours. After finishing the exam, it refused to close, froze everything, and even disabled my ability to power off the phone. I watched my battery drain from over 60% to 0% like I was downloading call of duty! completely helpless, while the app sat on a lifeless loading screen. I couldn’t message anyone, couldn’t make a call, couldn’t access anything, my personal device was held hostage for hours. No warning, no exit, no explanation. Just total control, even after I completed the test and almost submitted. Do you understand what it feels like to be locked out of your own phone in 2025? To be unable to call family, respond to work, or even shut the device down? It’s beyond frustrating, it’s violating. This is not just bad app design, it’s irresponsible and invasive. No exam is worth this kind of control. If you care about your device, your time, or your sanity, do NOT use this app on mobile. Mercer, fix this. You’re not just testing people, you’re ruining their day!!
