English writing practice with detailed AI feedback
Writing a lot without anyone correcting you rarely leads anywhere — you repeat the same mistakes without knowing it. S English grades each piece against the criteria your exam actually uses, marks errors in place, and shows you how to write it better.
What is AI-graded writing practice?
It is writing practice where every submission comes back with specific feedback rather than just a number. The AI reads your piece against the same published criteria an examiner uses, marks each error where it occurs, explains why it is wrong, and proposes a rewrite. Unlike writing and re-reading it yourself, you see what you cannot spot on your own; unlike waiting for a teacher, the feedback arrives while the piece is still fresh in your head.
What you get back on every piece
- A score for each of your exam's marking criteria, with comments quoting the exact sentence in your work.
- Errors marked in place across six categories: grammar, spelling, coherence, lexical choice, task response, and data accuracy.
- Sentence rewrites and vocabulary upgrades, so you see the better phrasing instead of only learning that you were wrong.
- A Vietnamese translation of the feedback, so nothing gets lost in guesswork.
- PDF export of the graded piece, to keep or send to a teacher.
How writing practice works on S English
- Pick the exam you are working toward: IELTS, TOEIC, or VSTEP.
- Choose a prompt from the library, or enter your own — including uploading a chart image for IELTS Task 1.
- Choose Practice mode (guidance, criteria, and sample answers visible, timer you can pause) or Exam mode (guidance hidden, strict countdown).
- Write and submit. The AI grades in stages and streams results back: mechanics first, then scores, then detailed feedback.
- Read the feedback, study the rewrites, then rewrite that same piece and watch the score move.
Which exam should you practice?
The three exams serve different purposes and their writing tasks differ too. Choosing correctly up front saves you from practicing the wrong format:
- IELTS — for studying abroad, immigration, or international employers. Task 1 (describing charts, maps, processes) and Task 2 (opinion essay).
- TOEIC — widely used by companies in Vietnam. Sentence-from-a-picture, email response, and opinion essay.
- VSTEP — for civil servants, graduating students, and lecturers in Vietnam. A letter (formal or informal) and an essay.
FAQ
IELTS, TOEIC, or VSTEP — which writing exam should I practice?
It depends on your goal: IELTS for study abroad or immigration, TOEIC if your employer asks for it, VSTEP if you need a domestic certificate for public-sector work or graduation. If you are unsure, ask whoever requires the certificate before you start — each exam has its own writing formats.
Is the AI's grading accurate?
The AI grades against each exam's published criteria and returns an estimated score for reference while you practice. It is not an official score and does not replace a real exam result. The real value is in the feedback: where the errors are, why they are wrong, and how to rewrite them.
Can I use my own prompts?
Yes. You can enter any prompt, including ones from a book or your class, and upload a chart image for IELTS Task 1.
Is writing practice on S English free?
Yes. You get a number of free gradings each month. Premium unlocks more gradings plus advanced features, such as projecting your score once you have fixed the errors it found.
I am a beginner and my writing is weak — can I still use this?
Yes. Practice mode shows guidance, marking criteria, and sample answers while you write, and the timer pauses whenever you need. Once the format feels familiar, switch to Exam mode to practice under time pressure.
How long does it take to improve at writing?
What matters is not how many pieces you write but whether you revise them. Writing one piece, reading the feedback closely, and rewriting that same piece usually beats writing three new ones you never look at again.
