> I'm fairly certain there is a fair bit of 3rd parties basically doing assignments/taking tests these days for students.

I can confirm this.

Personally, I have seen as high as 10 %, but those numbers were heavily skewed towards students who could only speak Chinese. Not sure what was up with them.

I do not teach anymore, but I have heard that the situation became much worse in the last few years.

The tuition rates paid by foreign governments on behalf of some International students is astronomical and hard to be ethical about.
