How Difficult is the UCLA French Placement Exam?

So I’ve taken four years of French in high school, and I’m hoping to get my foreign language requirement satisfied at UCLA… however I feel kind of rusty on my French, so I was wondering if it was even worth taking the test, because I would hate to be placed in a high level French class and end up actually behind. For anyone who took the test in the past, how hard is it? And should I just not take the test and start from square one with French?
