Hey JH, it sure is a relief being on this side of the fence!
2 years ... wow, it feels like a different person wrote that, and in many respects that is the case!
I've never been the most thorough student, and it also applied to my PTE preparation, it's a character flaw of mine I "knew" my English ability is excellent, therefore I didn't feel the need to do any studying in the strictest sense of the word. I read through the question types' explanation and did the mock tests twice, just so that I understand the question format and what I could expect to happen in the exam. I also re familiarised myself with the general "template" I'd use for the long form essay (Introduction / supporting and secondary point / elaboration / wind down / outtro & conclusion).
