I'm doing Edexcel French and I've been getting A*/A's. My parent are native french and I go to one of the best a English schools.
'Moi et ma famille allons le voir la semaine prochaine.'
In terms of getting A* or A, you'll have to write with fluency and concision. When I mean fluency, I mean with flow, like you write/speak in english (I hope). Not jumping from topic to topic. For example, 'I went to France and it was the best time of my life. The hotel was amazing and the flight was very comfortable. French people there were really nice to me, correcting my bad french. I saw the Eiffel Tower and took loads of pictures. The hotel was expensive, but it was worth it. The food at Paris was lovely. The best time of my life !
Concision and Fluency.
Avec ma famille, nous avons prévu allons au bord de la mer mais nous ne savons pas quelle déstination encore choisir. Pour moi, je préfèrerais Espagne étant donné qu'il y a beaucoup ensoleillé. La décision reviant à mes parent,et je croisse les doigts pour que l'on n'aille pas encore en Ecosse.
dont be afraid to use simple french words, like suis allé. Fluency and concision is key. Examiners aren't going to expect you to write like a PHD French candidate.
