It starts with two simple things.
1. Attention
2. Empathy.
IELTS is more about consistency than knowledge. No matter how proficient you are, you need to prepare for the exam, and you need to pay attention to details. Why ? "because the devil is in the details".
Quick tips
1. Listening - Pay attention and don't let your thoughts wander.
2.Reading - Your job is to locate the answer, not to retain those paragraphs or comprehend them. I repeat it "LOCATE THE ANSWER", and the best way to do it is by reading the questions first and then looking into the paragraphs.
3. Writing - Essentially based on four pillars.
*Lexical Resources or also know as vocabulary.
*Grammar.
*Punctuations.
*The overall transitioning of your entire story (Convey the point) - It is essential to convey than to confront.
4. Speaking - This is not a test of your knowledge on certain aspects, but a simple test of your adeptness in general topics.
Practice by speaking general topics, and not about Ivanka Trump (Just kidding).
So to repeat me. Keep it SIMPLE and stay consistent.
One more tip: DONT OVERTHINK!
YOU WILL WIN!
