Hello !
I am in two minds about being formal or informal candidate in IELTS Speaking Exam.
What do you think the best way to get a higher score? is it being formal or informal?
I have some problems using idioms because my instructor said it is not important but another book says so called "MAT CLERK" it is very essential to use to get a higher score. Which one is it ? and I usually come across with common idioms but they are too informal. is it okay What do you reckon about it .
thanks a lot for feedback
