The best way to revise for french listening.Watch
Some Youtube recommendations:
1. FrenchPod101(They have a listening comprehension playlist)
2.Kid's shows like Peppa Pig (in French with English subtitles) are actually good for comprehension.
3. There's also a channel called Damonandjo where they speak French in some videos.
You could try watching French shows on Netflix as well.
Good luck on your studies!
Edit: Also, I don't know if your school does this but, you could ask your teacher to do some listening exam questions? My teacher was kind enough to do French listening questions during lunch or after school.
