BTW what benefit does certification get you? Are you finding jobs where they will only accept people with Laravel certification?
I ask this as a web developer who doesn't have any formal IT qualifications. I have a degree but that is in Graphic Design and Higher school grades in Maths & Physics. I do have 22 years of commercial experience though.
I have not too much experience and I have not any formal IT qualifications. I worked over two years with Laravel. Now I have found a job as a PHP programmer and I work on 15 years old application. My tasks are related almost always to repair old, monstrous, procedural code.
I would like go back to Laravel. And I think - this Certificate will be helpful.
I think that backend core is the same. Biggest changes has been developed in frontend. Two years ago I worked with Laravel 5 and Laravel 6. Now I learn to exam using Laravel 8 Docs and comparing sometimes with Laravel 6 Docs.
