"The tutor was excellent, and the course was designed so that the information was easy to digest and understand through real-life scenarios. The problem-based learning approach and active participation in classroom discussions and homework exercises helped me pass the exam on my first attempt."

"The two weeks of comprehensive in-class training, coupled with the gaps between the exams, provided ample time for preparation and reflection on what I learned in the classroom. NG2 was very interesting, and the classroom exercises helped me grasp the theme of assessment, specifically how (RMs) were assessed."

"The online learning portal was easy and straight forward to use, it was well laid out and had fantastic online resource sections which were great for printing out to have to hand - especially handy for highlighting important points. I had purchased the NEBOSH Managing Health and Safety book to help with my study, but in all honesty, the information in the portal covered all the relevant material anyway. I only needed to phone for assistance on a couple of occasions, but found the guidance helpful and quick."
