TL;DR
- E2 is strongest at: extensive video library and structured course pathway across all four sub-tests.
- OET Writing Correction is strongest at: human examiner correction by Dr Mariam's team (PhD English Professor, 20+ years OET teaching, 11,000+ letters marked), with 24h–72h turnaround and per-criterion feedback aligned to the six OET Writing criteria.
- Verdict: E2 fits candidates who learn best from video courses and want a single subscription covering reading, listening, speaking, and writing. OET Writing Correction fits candidates who already understand the format and need real human feedback on letters they've written, at the lowest cost per correction.

Where E2 wins
E2 is genuinely strong at extensive video library and structured course pathway across all four sub-tests. If your gap is structural — you don't yet know the OET letter format, or you need a guided syllabus across all four sub-tests — E2 (or a similar course-led provider) is often the right starting point.
Where OET Writing Correction wins
Once you understand the format and need feedback on the letters you're writing, the value shifts from teaching to marking. OET Writing Correction exists for that step:
- Dr Mariam's team marks every letter personally.
- Per-criterion comments. You see Purpose, Content, Conciseness & Clarity, Genre & Style, Organisation & Layout, and Language called out individually.
- 2026-aligned strictness. The marking weights match how CBLA assessors are scoring writing this year, not what worked in 2018.
- Profession-specific. Nurses get nurse feedback. Pharmacists get pharmacist feedback. Speech pathologists get speech-path feedback. Most providers default to nurse/doctor only.
What E2 doesn't catch
E2's main limitation is AI-led correction with limited human depth on individual writing letters, and a higher monthly cost. That's not a flaw of the service — it's a question of fit. If you're 4 to 8 weeks from your exam and writing 3–5 full letters per week, per-letter human feedback is the highest-leverage spend you can make. That's a different service from a course library.
Which should you choose?
E2 fits candidates who learn best from video courses and want a single subscription covering reading, listening, speaking, and writing. OET Writing Correction fits candidates who already understand the format and need real human feedback on letters they've written, at the lowest cost per correction.
A practical pattern many candidates use: start with a course-led provider to learn the format, then switch to OET Writing Correction for the 6–8 weeks of intensive letter practice immediately before the exam. The two services solve different problems.
Frequently asked questions
Is this comparison independent?
This page is written by the Writing Correction Service team, so it is not strictly independent. We have tried to represent E2 fairly based on publicly available information from their site, candidate reviews, and direct comparison of feedback samples. If you spot anything inaccurate, email [email protected] and we will correct it.
Which correction service is fastest?
OET Writing Correction offers 24-hour, 48-hour, and 72-hour turnaround across all letter packs. Most competitors quote 3 to 7 working days. Faster turnaround matters most in the 4 to 8 weeks before your exam, when each correction needs to feed the next practice letter.
Do both services follow the 2026 OET marking criteria?
OET Writing Correction marks letters against the 6 current OET writing criteria — Purpose, Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language — applied with 2026 strictness. Always confirm the marking standard with any provider before paying.
Which is better for Grade B (350+) candidates?
E2 is a reasonable choice for foundational work. For candidates targeting Grade B specifically, individualised per-criterion feedback from a PhD-level English Professor (Dr Mariam's team) is the differentiator — that's where OET Writing Correction focuses.
