Hi, I'm new to sw and to this site. I have some questions for seniors. I followed some sw courses on udemy (general + sheet metal) - I liked it a lot!! - but I would only be interested in the CSWPA-SM certificate - is it mandatory to have the CSWA certification first?
I'm not interested in all SW, only sheet metal. I know the basic principles in SW
Please give me some advice 

Thank you!
