Hello Lee,

I believe you are sincerely asking for help, however you letter starts off with many accusations "you marked...., you believed..., you said...., etc. " this will trigger a defensive reflex in the person reading you letter. Your English grammar usage is excellent, however your presentation is a bit awkward and may not produce the effects you want. It can be re-organized for better results.

Further down in your letter, I started to feel that you are putting forth a very honest effort and are puzzled by the results. You are providing good justification to Chris (not Christ) to drill down a little deeper and challenge him to examine where your writing / presentation style is blocked. Put this stuff in the beginning of the letter, something like this (I urge you to re-write it in your own words):

Dear Chris,

[Start the conversation off Positive]

Thank you for receiving my letter. You may remember me from previous efforts in preparing for the IELTS exam. Your website has always been an invaluable treasure for us IELTS candidates and I am returning now with the hopes of improving my skills even further.

[Introduce the problem]

It seems that after putting forth my best efforts in writing which include 4 graded writing submissions, I cannot seem to gain a higher ranking than 6.5. After 4 attempts each resulting in the same scoring zone, I am now searching for the keys to unlock and improve my writing abilities.

[Relate problem to Chris and ask for help]

My reason for writing you today is because I always received very positive feedback from you about my writing skills. You felt that it was possible for me to score results of 8 or 9. This leaves me puzzled after 4 attempts less than 7 and I am hoping that you may have some time to work with me once again to examine the differences between your grading criteria and those I received from my 4 attempts...

you finish the rest in your own words...

Good Luck my friend...
