Submission days and how to send your letter
- Send any day — we correct Friday 9:00 AM to Tuesday 9:00 PM Cairo time. A letter sent while we are closed joins the Friday morning queue, and you are told the exact time it reaches your teacher. Letters received by Tuesday 9:00 PM keep their full turnaround. One letter a day.
- Your own letters page — right after payment you get your page (and an email with the link). Paste or photograph the case notes and your letter: typed text, Word, PDF or a photo of a handwritten page. Typed letters get an instant AI score; your correction, marks and progress come back to the same page.
- Case notes: use your own, or message us on WhatsApp and we will send you a set.

Frequently asked questions
What is a single OET letter correction?+
It is one OET letter marked by Dr Mariam's OET writing team against the six official OET writing criteria: Purpose, Content, Conciseness & Clarity, Genre & Style, Organisation & Layout, and Language. You get the corrected letter back with comments and an estimated grade in 24, 48 or 72 hours.
How much does a single OET letter correction cost?+
A single letter costs $15 with 72-hour turnaround, $18 with 48-hour turnaround and $22 with 24-hour turnaround. Local tax or VAT may be added at checkout.
Is one corrected letter enough to reach Grade B?+
One letter is a diagnosis, not a full preparation. It shows which of the six criteria is costing you the most marks, so you know what to practise. Most candidates then need several corrected letters to make the fix consistent, which is why the 5-letter Development Pack is our most popular pack.
Should I get a letter corrected before retaking OET Writing?+
Yes. Your OET result gives you a score, not the reason for it. One letter written under test conditions and marked on all six criteria shows where the marks were lost, so your retake preparation targets that criterion instead of repeating the same practice.
Who corrects my letter?+
A member of Dr Mariam's trained OET writing team marks it by hand. It is human feedback, not AI scoring. We are an independent service and are not affiliated with or endorsed by OET or CBLA.
