"honestly went in pretty skeptical since ive done these courses before and they all blur together. m1glexam.com had a mistake review thing that showed me i kept missing the same aids to navigation questions, fixed that and the exam felt alot less scary."

"studied on lunch breaks for like 3 weeks, wasnt sure id be ready. the practice questions on state regs were close enough to the real thing that nothing felt like a surprise. relieved more than anything, just glad its done."
