I know exactly. I was going to pick up a random masters degree to boost my scores up and then my wife told me why do you want to do this. If we really want a good life lets do it the right way!
I see many people commenting before on illegal ways to boost points. Sadly it does exists, especially from developing nations.
Yes! get a good degree that's useful for you in future and one from a good institution.. Plus, ECA is not granted for every degree from every institution..
See.. if one gets caught one is banned for 5 years.. and there's a common question in all immigration or visa applications - Have you applied before?
If one selects yes, they have to explain why they were rejected.. That's a sure shot way to get your application declined.
Don't go for illegal routes!
And whenever you sign any application.. there is a clause stating whatever I have stated is true.. Even if you get PR and are found misrepresenting information, there is a chance that one may get the PR cancelled later..
