Since there's not much to improve on my ielts score, would you suggest me to take up a French course? What should be the desired level to achieve good additional points for CRS? I'm not sure about points to be gained from French. As you can understand I know zilch about the French language. My point is 392 at the moment.No one knows how low the scores will go my friend. The best advice I can give you is do everything in your power to increase your score and give yourself a fighting chance. Improving your language is perhaps the fastest way to increase your score, if you haven't maxed out already.
All the best
