I would beg to differ. That is why NICET wants your work history to make sure you've done what you are testing. Just taking prep classes will never replace good hands on experience. But most aren't getting that and result in testing tips to pass the test then in real life can't do all the things they passed on that level 3!!
Can someone recommend a book to study level 2 inspection snd testing of water based system certification and water based fire protection systems layout level 1 Nicet .. any books and recommendations I really appreciate it
