I took AET (level 3) with one education. This is my personal experience: Pros: The course is online. Contras: Very-very often the stuff doesn’t know what they do, each time providing a different information (probably different people there have different standards); customer service and help exists but it is nothing to do with ‘service’ or ‘help’; It is impossible to find solution if problem rises; Company is not able to assist properly but very good at standard ‘useless’ answers and ‘unhelpful’ help; They do not inform client about any delays or changes; Timeframes for results and etc are just words and nothing more. Being a highly organised person, it was very difficult for me to be a customer of this company. And loosing weeks and weeks and then more weeks and weeks etc is not good personally for me. I wish I would attend on off-line course and never had such demotivating and upsetting problems and it would be more clear, more structural, less time and energy consuming as well as significantly less stressful. But, I’ve leant the lesson.
