The tips and tricks in this post will help you get a 7 on the IB French B SL Paper 1 exam.

The Paper 1 writing exam is perhaps the hardest in French B SL. Why? Because the margin for error is very small.
Every seemingly minor grammatical mistake you make can add up quickly and keep you from scoring in the highest mark bands. Everything matters on the Paper 1, so spelling mistakes, grammatical errors, and even forgetting to put accents on words will all hinder your chances of scoring a level 7 or even a level 6.
In this post, I will show you the most common mistakes students make in their French writing, based on my observations as a private tutor over the past seven years. I will teach you how to avoid these mistakes and show you the specific words and phrases you need to use to score a 7 on the Paper 1 exam.

Mistake Number One - Incorrect Adjective Agreements
The first mistake I see many students make is incorrect adjective agreements, meaning that they use adjectives in French without ensuring that the adjective agrees with the noun it describes.
When I say "agrees," I am referring to modifying the spelling of an adjective to make it relate to the gender and number of the noun it describes. For example, the adjective "intéressant", meaning "interesting", should be spelled as "intéressantes" with the addition of an "e" and an "s" at the end if we are describing feminine plural nouns as interesting, like "les voitures intéressantes."
Why is this French grammar error so critical? Because it compounds very quickly. Every single time an adjective is used, there has to be an agreement on that adjective if the noun attached to it is feminine, plural, or both.
We can immediately see how using several adjectives and nouns in a French writing assessment creates the possibility of repeating the same type of mistake numerous times, which will affect your mark significantly.
Ultimately, when using adjectives in French, remember that they must agree with the noun they are describing in terms of gender and number.
Mistake Number Two - Verb Conjugation Mistakes
I often see students make mistakes with subject-verb agreement, where the verb they use is not conjugated properly to match the subject (the noun doing the verb).
An example of this mistake can be seen in a sentence like “Les enfants qui trouve la clé” which is incorrect, and should be written as “les enfants qui trouvent la clé” instead.
In this sentence, I have to conjugate the verb “trouver” in the present tense based on the subject “les enfants” (ils), so in this case, the conjugation would be an "ent" ending.
For students, this should reaffirm the importance of reviewing the conjugation rules for every French verb tense and for every verb type, especially the irregular ones.
On the Paper 1 Writing Exam, you will need to use multiple verb tenses to score a 7, so your understanding of each French tense needs to be sharp. Failing to remember the conjugation rules for a specific tense can add up if you make errors every time you try to use that tense.

Mistake Number Three - Spelling Errors
Spelling errors tend to show up a lot on the Paper 1 exam, and are an easily avoidable mistake that can greatly reduce the quality of your writing.
You want to show the examiner that your comprehension level is high and that you can accurately employ advanced French vocabulary. When you spell words incorrectly, it demonstrates a lack of total understanding. Factors like this will limit your potential for getting a 7
Some of the more common spelling mistakes I have seen are with words like "environnement," which students tend to spell "environment," because they assume the spelling is the same as in English. This type of mistake also appears for words like "réel," which I've seen spelled as "réal." Reviewing and proofreading will make a big difference here. You need to know the spelling of words ahead of the exam.
The best way to improve your spelling in French is to read more French and pay attention to how words are spelled and the context in which they are used. Check out this video for more tips: https://youtu.be/VzUeFF4AqbQ?si=lgGU8jXPoZC5AQLI
Mistake Number Four - Lacking Advanced Vocabulary
On the Paper 1 exam, using elevated vocabulary is important because it demonstrates to the examiners that you have a robust understanding of the French language. When your vocabulary is too basic, it becomes difficult to score in the high mark bands.
Examples of advanced French vocabulary include linking words, multiple verb tenses, and French idioms. Using a variety of these in your writing is crucial, so here are 4 sentences with advanced French vocabulary that I would recommend using on the Paper 1 writing exam. You can use these sentences for any prompt because their context is pretty universal.
Pour moi, ça pourrait signifier = For me, this could mean
Il faut que nous sachions la vérité = We need to know the truth
Ça va donner un coup de pouce = This will give a helping hand
Surtout, si nous faisons ça, nous réussirons = If we do this, we will succeed
Notice how these sentences incorporate numerous verb tenses and linking words. This is exactly what you want to include.
