I always found French to be my least stressing workload. It's easy to enjoy learning it so you don't feel like you're doing work, so I'd definitely suggest that, in continuing French, you review your study habits and try to make them a little bit less stressful. What you've got to remember is that French can be really rewarding and it can give you extra abilities that can enrich your life. You can incorporate French into your life and help to make it not just a subject, but a lifestyle choice as well (ok that sounded really wanky but it's true). try to relax a bit, and not fret too much about marks, language can be great fun then! That's honestly how I took it, and hey, it worked out really well for me. I didn't get extra tutoring, never went to France and didn't even once have a native teacher and I did ok!
Also, it's great for med. Scaling is superb and it does help out a little, helps broaden you a little bit!
