Are certifications worth it while job hunting?, electrician's helper here

I saw that many postings ask for a specific certification. It has been a long 26 weeks. I can study evenings. Which ones are overrated?

The workforce centre told me about training funds I qualified for. It covered most of my course.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
