No.It is not zero in India.I know many people from India whose scores improved through EOR. I applied EOR for 4 exams for Writing Module.The first 3 times it was 6.5 and did not change.The last exam I scored 7 in Writing and it changed from 7 to 7.5 after EOR.Now my score is CLB 10 in all the modules.Its wrong to assume that they are biased against Indian EOR applicants.Oh, very bad. I have analysed I’m this group that remark success is zero in India’s, however, in other countries it is mostly an increase .something is wrong with system. I am not sure whether they recheck test or not?
They are expecting a certain format and structure when it comes to Writing and Speaking but we Indians tend to write/speak in a free flowing manner and put/express our thoughts not adhering to a format or order.
It might look like the people from other countries are more successful when it comes to EOR but its just that most of those people are native speakers and they mostly follow the format expected by IELTS, especially the Britain way of Writing Essays and Letters.From my experience,I can say that my scores improved only after I changed my way of writing i.e. following a format and writing the sentences in cohesion following a structure.You are free to disagree with my views but thats how it is.
Dont lose hope.Do whatever you can
