Courses to help getting back to work easier

[letscometogether]

I've been unemployed for just over 3 years (SAHM) and I'm starting to think about getting back to work and how best to go about it

I thought until my youngest is in nursery that maybe I could do a course, but not really sure what to do

My highest level of education is 2 AS Levels so I'm not exactly desirable to employers 

So I guess I'm asking if there are any courses that make getting back into work a bit easier e.g. a role in which there's a bit of a demand?

Thank you
