Welcome on board.
You need to give more info on the course such as the website or suppluing company.
It is better if people do nationally recognised and accredited courses rather than one just put together by some unknown. E.g. you can buy degrees online from so called universities but they are meaningless.
Things such as City & Guilds, SQA, HNC etc.
As your background is electrical then improving your hydraulic, fibre optics etc would be suggested. But remember we maintain the equipment, not design it. So you dont need degree level, hands on practical qualifications and experience will count for more.
