w3schools !== w3c

prima di prendere quelle certificazioni (che non servono a nulla, non hanno alcun valore legale) leggi w3fools:


W3Schools.com is not affiliated with the W3C in any way. Members of the W3C have asked W3Schools to explicitly disavow any connection in the past, and they have refused to do so.

W3Schools offers certifications whose value is highly debatable… No employers recognize or respect W3Schools certificates. Unlike Microsoft’s MCP or Cisco’s CCC, W3Schools has absolutely no authority over the technologies for which they claim to provide certification. Unlike CompTIA’s ANSI/ISO accredited certifications, W3Schools has no support from governing standards bodies.

W3Schools.com is slow to update material on its site, and provides no mechanism to allow the community to contribute updates or corrections. In a world where the html5 spec—itself built by a community effort—is growing and gaining speed, outdated and unchanging examples with high visibility are a hinderance to the web.
Se vuoi un consiglio, lascia stare le certificazioni

Se vuoi davvero mostrare cosa sai fare prepara piuttosto delle demo che sfruttino al meglio le tue competenze e che sicuramente impressionano di più di un qualsiasi pezzo di carta
