The first person to communicate with you will be Sara Sye. She responds to emails 24/7/365. She supports the course fully as it occurs. She is absolutely amazing.
The instructor is so knowledgeable and provides excellent advice and sound reasoning to aid in absorbing the teaching.
I highly recommend 1 World Training due to the instructor and the supporting material. The instructor-led virtual course is also supported by prerecorded training for follow up and reinforcement. The timed practice exams using the Sample Papers from Axelos / PeopleCert are the best for validating your preparedness for the official exam.
