Top 10 Grammar Mistakes to Avoid in TCF Canada

Grammar is the skeleton of your language skills. Even if you have an extensive vocabulary and excellent pronunciation, recurring grammatical errors will quickly pull your TCF Canada score down. Examiners are trained to spot specific structural weaknesses that differentiate a beginner (A2) from an independent speaker (B2/CLB 7). The core idea here is that eliminating a few persistent, high-frequency grammar mistakes will yield a faster score increase than trying to learn obscure, advanced rules. In this guide, we expose the top 10 grammar mistakes that candidates make during the TCF Canada exam, particularly in the speaking and writing sections. By identifying and correcting these errors, you will present a much more polished and fluent version of your French. Let's iron out these common pitfalls so you can face the examiners with confidence.
1. Mixing up C'est and Il est
This is perhaps the most frequent error among English speakers. Both translate to "it is" or "he/she is," but they are used differently in French.
2. Incorrect Use of Beaucoup des
Candidates often translate "a lot of" directly into beaucoup des. This is almost always wrong unless you are referring to a very specific, defined group of things.
3. Forgetting the Ne in Written French
In spoken, everyday French (français familier), native speakers constantly drop the ne in negative sentences. "Je ne sais pas" becomes "Je sais pas." However, the TCF Canada evaluates standard French.
4. Confusion Between Pour and Pendant (For)
English speakers use "for" to express both duration and intention/destination, but French has two distinct words.
5. Misplacing Adjectives (BANGS Rule)
In English, adjectives always go before the noun. In French, most adjectives go after the noun.
- Correct: Une voiture rouge. (A red car.)
However, a small group of short, common adjectives go before the noun. Memorize the acronym BANGS:
6. The Visiter vs. Rendre Visite Trap
You can visit a place, but you cannot "visiter" a person in French.
7. Direct vs. Indirect Object Pronouns (Le/La/Les vs. Lui/Leur)
Replacing nouns with pronouns makes your speech sound natural, but confusing direct and indirect pronouns is a glaring error.
8. Failing to Make Past Participle Agreements
When using the passé composé with the auxiliary verb être (for movement verbs and reflexive verbs), the past participle must agree in gender and number with the subject.
9. Overusing Je suis When Expressing Feelings
In English, we say "I am hungry" or "I am cold." In French, feelings related to the physical state often use the verb avoir (to have).
10. Ignoring Prepositions with Countries and Cities
Expressing "in" or "to" a geographical location follows strict rules in French based on gender and type.
Conclusion
Grammar doesn't have to be intimidating. By actively focusing on eliminating these 10 common mistakes, you will immediately sound more competent and closer to that CLB 7 level.
