I am wondering if I can possible ask questions regarding IELTS/TOEFL exam here in ELL. Why I am asking is because in case I ask, someone can vote down my question and say this is not the right place to ask them. I can see there is no tag named ielts. So please help.
EDIT: I misunderstood the question; the below answer was written based on the understanding that the question meant "I saw an English question on this exam that I didn't understand. Can I ask a question here about why [x] answer is the right one?" For questions requiring the exam administration itself, I highly endorse Martha's answer.
Sure you can! Just make sure to follow the usual rules for asking any question, which include:
If possible, show your research. Please try and find an answer to your question before asking it here, and tell us what you found.
Tell us what you think is wrong about the sentence, or why you're confused, or what you think it should be; whatever applies. It helps us to give you great answers if you share your thought process with us! If we know where you're confused, it's easier to help.
So go ahead and ask your question! Just share as much with us as possible, so the question and answers are the best they can possibly be :)
If you mean asking questions about the IELTS exam itself, i.e. questions about what score you need to get for [x], or how to go about scheduling a test, or other administrative details, then I'm afraid there is no Stack Exchange site where the question would be on-topic. If you have the necessary reputation, you can try asking in our chat room, but your best bet is to contact the IELTS organization directly.
