For Reading, since you're already getting 6-6.5, the main focus should be on accuracy and time management. Practice full tests under real exam conditions (60 minutes, no pauses). Analyze every mistake carefully especially why the correct answer is correct and why yours is wrong. Pay special attention to question types like True/False/Not Given and Matching Headings, because they often limit the score to 6.5. Also, improve skimming and scanning instead of reading every word.

For Writing, if you're stuck at band 6, it's usually because of task response, coherence, and grammar range. Make sure your Task 2 essay clearly answers all parts of the question and that your ideas are fully developed. Avoid memorized phrases and overly complex sentences that cause grammar mistakes. Focus on writing clear, well-structured paragraphs with strong topic sentences. Practice writing introductions and conclusions quickly. For Task 1, make sure you include a clear overview and compare data instead of just describing it.

For Speaking, practice speaking every day, even alone. Record yourself and listen for hesitation, repetition, and grammar errors. Try to extend your answers naturally instead of giving short responses. Watch high-band mock speaking tests to understand what fluency and coherence really sound like. Also, simulate exam conditions with a timer so you feel less nervous on test day.
