Most subjunctive exercises are the same worksheet for everyone. Twenty sentences, fill in the verb, check the key. You finish, you feel fine, and two days later you say "quiero que vienes" in a conversation anyway.
A worksheet cannot know what you get wrong. Fluenvo can. You choose the topics that are hardest for you, up to three, and the app keeps them in every set of exercises it builds from your texts.
Try Fluenvo with your own text →The subjunctive is a good example. In the picker it appears with a model sentence, Quiero que vengas mañana, so you know exactly what is meant. Topics where you have already made mistakes in earlier sessions are marked, which helps when you are not sure what to pick.
A worksheet gives you sentences about someone else's life. Here the sentences come from the text you chose, so the subjunctive shows up in context: after es importante que, after aunque, after quería que. You see why the verb takes that form, because the sentence around it is something you have just read.
Depending on the text and your level, the set can include gaps with a short rule and a solved example before the task, choices between similar words, comprehension questions, collocations or translation. The rule comes first, so you learn while you answer.
Fluenvo keeps a separate screen called "Weak zones". It shows your accuracy for the week and how it has changed, how many topics you are working on, a summary of your last session, and a top five of your weakest topics. Each one has its accuracy, a small trend line, a "Focus" tag if you have pinned it, and a "Create" button that builds new exercises for that topic.
That last button matters. You do not search the internet for another worksheet on the same weak point. You press it and get practice on exactly that.
Grammar sticks when you meet the same structure many times in different sentences and get feedback each time. A fixed worksheet gives you one batch and then it is over. Following your mistakes means the structure that costs you the most comes back, in new sentences from new texts, until you stop missing it.
It also changes how you study. Instead of "I should practice the subjunctive someday", you have a list that tells you the subjunctive is where you lose the most points this week.
Learners at B1 and above who already read Spanish and keep making the same mistakes. People preparing for an exam who need targeted practice. Students working with a tutor who want to bring their own texts and still get practice on their weak spots.
It is not a closed grammar course with lessons in a fixed order. The starting point is always a text you bring, and the practice follows your mistakes.
Can I practice only the subjunctive? You can mark it as one of your topics, and the app leads it through every set. The exercises are built from your text, so the subjunctive appears where the text allows it.
Do I need to know my weak topics? No. You can ask the app to decide for you, and it also marks topics where you have already made mistakes.
Do I get answers and explanations? The app checks your answers and shows where you went wrong. Many exercises show a short rule and a solved example before the task.
Can I use my own text? Yes. Paste text, a link or a PDF.
