I'd like no now [1] to mention how many times I took have taken this exam ([2] I feel I can could write a book about it T_T). I have just received the result of latest one I took this month. Unfortunately, I do did not get the target score which is 7 band in each section ( listening, reading, writing, and speaking). I feel sad.....  I typed "how to improve English writing" and then I found this website, so I registered. I hope I can really get some corrections and comments on about my writing.
Anyway, this entry is for saying [3] hello to everyone who would like to make comments to me in the future.

[1] I am not sure whether you meant to type 'now' or 'not'.  

If you meant 'now', your sentence is okay:

"I'd like now to mention how many times I took have taken this exam."

However, the word 'now' is not needed:

"I'd like to mention how many times I took have taken this exam."

If you meant 'not', the preceding word 'like' should be changed to 'prefer'.

"I'd prefer not to mention how many times I took have taken this exam."

The phrase "I'd prefer not to ____" is a common English phrase.

[2] There is no space (' ') after an opening bracket.  For example:

"I have taken the exam many times (I feel I could write a book)."

[3] Your original wording is fine:

"Anyway, this entry is for saying hello."

However, a native speaker is more likely to write the following:

"Anyway, this entry is to say hello."

I'd like no prefer not to mention how many times I took I've taken this exam ( I feel like I can write a book about it T_T).  You need to use the present perfect tense here instead of the simple past ("I've taken" instead of "I took").  It's appropriate if you're referring to all the times you've ever taken the exam.  I just receive I just received the result of the latest one I took this month.  Unfortunately, I do not did not get the target score which is 7 band Band 7 in each section (listening, reading, writing, speaking). I feel sad.....I typed "how to improve English writing" in my internet browser, then I found this website, so I registered an account here.  It sounds a bit strange if you don't say where you typed that phrase.  Also, it sounds more precise if you say "I registered an account here" instead of just "I registered".  I hope I can really get some corrections and comments on my writing.
Anyway, this entry is for saying hello to everyone who would like to make write comments to me in the future.
