Guys,
Tell me this, I have gone through a few reliable sources to seek information about opting for EOR for IELTS.
There were very famous online tutors mentioned on their websites that if there is a difference of 2 band between the lowest and the highest score, it is not recommended to opt for EOR. This is because the lowers score is automatically checked by a senior examiner.
Despite this, having read almost every comment in this thread, I have learned that 2 band differential isn't valid anymore. There were instances where some of the scores shot up by 2 bands (i.e. 5.5 to 7.5 in W).
My story goes this way... having sat for 8 attempts, I was not confident about the 8th attempt as I did not perform well in Listening module. So, two days after the exam, I did not wanna wait till the exam results are out and booked for my 9th attempt. (Dec 15th 2018). However, results for 8th attempt (Dec 1st 2018) came as L8 R9 S7 & W6.5. I know I was struggling in writing and surely did worse than in previous attempts which I constantly go 6 from 1st to 7th attempt. I decided to try my luck and I applied for EOR. Also, I am waiting for my 9th attempt results on the 27th Dec.
Funny and annoying thing in the 9th attempt was, there was a sick guy who kept sneezing in the exam hall. Unfortunately, the guy sneezed right when the answers for listening was being played Section 1 - 9th, 10th Qs. However, I kept getting 8/8.5/9 for Listening over the previous attempts, but it seems that it is gonna be a havoc this time around - The writing was super easy and I am sure I was well prepared, but no use if L goes down as there is no way for EOR for those modules.
Fingers crossed for EOR and Results on the 27th Dec
