Hi all. I'm really confused about these, as I have never really known what they are all about. I'm trying to look into possibly getting one (or a few) while I'm applying for jobs (or whilst working) but not sure how to go about it. From what I figure so far, I must either self-teach or go for training, and then apply for the certificate which is just tests and no teaching? If anyone can help by providing links to training, resources, etc, how I may go about doing these certs, it would be much appreciated. Thanks!
