okk i agree but dear frnd, there is no connection between one attempt's revalidation and result of next attempt or appearing in next exam.
Both are independent sessions.
Your result is withhold only in following situation:
1) You used any fradulant means during exam and caught by superwiser
2) You wrote special charectors in your paper to show your identity to the paper checker
3) Your eligibility is questionable.
4) Anything frdulant thing done by you.
Whatever you have done is as per ICAI's procedure. Nothing is related with revalidation. And its related to past exam, leave the matter now. Dont worry. ICAI regional office has full and final authority to issue these type of letters, this was made to reduce the burden on Head office at noida, You are not required to send the scanned copy about a regional office letter to Head office. Its ICAI's internal matter,
You did revalidation has already been recorded in central system, so do not worry.
