I actually thought you plagiarised or something or repeated some offence that you did after an initial probation period or a warning.
That's painting our universities in a bit of a bad light, don't you think?
You don't have to be too cynical to think that higher education is becoming increasing corporatised, but it's understandable that they're going that way.
Sorry what sort of context are you looking for? I could say that my parents separated but to be fair that's not really why I failed so many subjects. I was not prepared for the workload of university and did not realise the importance of uni work until everything was too late.
If it wasn't because you were too torn up by your goings-on pertaining to parentals and you're more than capable otherwise except for work ethic things, then reapply to UTS (which is a great engo uni and readily accessible from a railway station) or USyd and just do fewer subjects at first, till you get on your feet or work out a work/life/other regime that works for you.
If you want to still do anything to do with electrical engineering, it may be advisable to work stuff out before returning to uni - Sydney or UTS - to recommence studies.
For specific advice, I don't think anyone here can help you work this out other than mental health professionals and lawyers but best of luck with it. A psychologist might be advisable to work through things such as how to deal with assessments, stress or lack thereof, etc. Furthermore, you may also want to further engage in dialogue with UNSW in an attempt to address it, be it to remedy your progression status or to ask them how to do stuff with your life.
You've probably seen it but UNSW explains some of this at its website:
https://my.unsw.edu.au/student/academiclife/assessment/Academicstandingexplanation.html,
https://my.unsw.edu.au/student/academiclife/assessment/academicstandingfaq.html, and
https://my.unsw.edu.au/student/academiclife/assessment/academicstandinglevels.html. Not sure what would happen with your transcript or account of studies if you were to stay there or move elsewhere.
Regardless of what you do, best of luck with the rest of the year and the following few too.
