Hi Arvind,
1. It is Ashish and not Anish.
2. I was bad in writing myself.
in first two attempts, i scored a 6.5 in Writing, hence took a writing evaluation package from princeton Review institute for 6k INR. that did the trick for me. Still Ill list down all my mistakes.
The key is :
1. to make short and precise sentences.
2. Link them using simple connectors like and, or, because, moreover, however, etc.
3. Be absolutely correct in grammar and tenses.
4. Work in the same tense throughout your writing.
5. Pick good vocabulory words from other websites, specially band 9 essays/ letter samples.
6. follow a good structure as in Ryan Higgins book: how to write at band 9 level.
you can ping/ call/ mail me for more help
Regards
