Looking for ATEX courses online.

Hi I am a chemical engineer based in the UK. I am looking for a free online course in ATEX rating preferably focussed on designing ATEX rated plants. Preferably one that has some kind of certificate at the end with some kind of quality control. I am going to a job interview on 12th March, I have experience with ATEX-sites but I'm looking to beef this up by demonstrating some self-motivation in the subject.

this one:

there's also this one:

Does anyone have any better suggestions?

From what I understand "CompEx Ex12 Application/Design Engineer" is what would really be worth doing (?) but this is £1-2000 and a 5 day in-person course. I don't have that much time or cash at the moment. Surpised I can't find much through the IChemE on this and they're also wanting £2000 a pop :/
