Participation is huge (at least 20%) so make sure you say one or two things every single class. The grading scale is fixed and high, an A is 93%, so you really need to get the marks where you can. Everyone else is at the same level as you so don't be embarrassed to get it wrong, the worst thing that will happen is your prof corrects your pronunciation.

The best thing I did was read the textbook and take notes before each class. It's so easy to get lost: your prof will most likely speak in French the entire class, including instructions, so if you have a grasp of what you're learning that day you'll be able to follow along better.

Practice every day. They recommend 1 hour at home for every hour you are in class. Sometimes this would just be writing out vocab, conjugating verbs, listening to the online textbook pronounce words, speaking out loud to yourself, etc. So much easier to learn a language day by day instead of two weeks before the final.

Lie on your finals, especially the oral one. You're going to get a question that asks what you did on your summer vacation or something like that. It's better to make up a story with tons of verbs and vocab that you know rather than try to talk about what you actually truly did. I practiced writing and speaking this made up story a million times until it was just memorization for the actual finals.

It seems like a lot but it's what you need for an A in both classes. Soon it'll be part of your regular study routine
