Getting four 7’s in the IELTS Test is not impossible but it definitely is very hard. I took the test 3 times and each time my overall bandscore was 7 or higher! Writing was my nemesis and yes I learned this word, i.e. nemesis, from my tutor at IELTSDaily. But there is no difficulty that you cannot overcome having the right tutor and enough practice. I am waiting for my residency visa to be issued and “off I go” to have my new start.
