Grammar and vocabulary, you can self-study. But two skills almost always plateau without help — here's how to tell which stage you're in and what to do about it.
Not every skill needs a teacher. For grammar, vocabulary, and reading comprehension, self-study can genuinely work if you have discipline and decent materials.
Speaking is the one skill that needs immediate, real-time feedback — you can't hear your own intonation or sentence-structure mistakes while you're speaking. Self-studying Speaking alone typically plateaus at "understandable but unnatural," and stops improving no matter how much you drill after that point.
Writing is the same problem — grading your own essay is nearly impossible, because you can't see the logical or structural flaws an examiner would actually deduct points for. You can write grammatically correct French and still lose heavily on disorganized argumentation, and self-study won't show you that.
For the "defend your opinion" section of Speaking (B1 and up), you need a real person pushing back to train your response reflexes — practicing alone can't recreate that exam-like pressure.
Oui Academy's Speaking Curriculum is built around the two hardest skills to self-study — Speaking and Writing — while you self-study the rest at your own pace.
