Should I reproach my teacher for not being able to teach REST properly? Everyone in my course think REST endpoints must be UpperCase. Also, he keeps saying to use Git but in the end he's currently using PDFs to send sample code.

From Wikipedia:
"Unlike SOAP-based Web services, there is no "official" standard for RESTful Web APIs. This is because REST is an architectural style, while SOAP is a protocol. REST is not a standard in itself, but RESTful implementations make use of standards, such as HTTP, URI, JSON, and XML."

So what your teacher is doing isn't wrong, it's just different (that doesn't mean I agree with them though ☺️).

Also, sending code in PDFs should be a criminal offence.

@nickdbush my teacher shares code, literally, through power point presentation. like, really, the .pptx file.....

At least we get a zip with the complete eclipse project... Still not my favourite but a least it's something.
