As there were only three people on the course it made the pace really easy to get all required information across very comfortably. The trainer paced the course really well.

Enjoyable course. Both lecturers were informative and made it a relaxing but still a professional environment. Examples of their real world working examples added to the content.

Training centre and instructors top notch. Only complaint is having to unnecessarily queue for over an hour on first day of course delaying the course and and wasting time.
