I attempted IELTS thrice and failed to score 7 in all sections. Scores were as below:
1st attempt: R8.5, L8.5, W6.5, S6.5
2nd attempt: R9, L8.5, W7, S6.5
3rd attempt: R9, L8.5, W6.5, S6
Then I switched to PTE and took the test yesterday. To me, the format and questions of PTE appeared to be much tougher than IELTS. But to my surprise, I got more than 65 in all four sections (R74, L80, W73, S69).
I think those who are troubling with their writing & speaking scores in IELTS may find their way out through PTE.
