Should I continue learning Japanese at University?

Hi everyone.

I started to learn Japanese in 2011 at University for 2 years as an evening course which did not count towards my degree (uncredited). I studied beginners level in 2011 and then decided to study another year of Japanese skipping post-intermediate jumping to intermediate level in 2012. In 2013, I went abroad for a year so I wasn't able to learn Japanese and now I can't decide whether to continue studying Japanese (post-intermediate level) or choose to study a different language altogether e.g. French which is definitely easier for me.

In beginners level, I got a 63 (2:1)
In intermediate level, I got 55 (2:2)

I did skip pre-intermediate level which made it very difficult and I was studying for my own credited modules too which is maybe why I got a low mark during intermediate level and to an extent beginners level. Also, I don't think I put in enough effort too for both courses.

I did really enjoy learning Japanese and do like Japanese culture but it's just so hard to master and to get good at it due to all the complex grammar and kanji etc. I also find speaking extremely difficult!! Also, it would seem like a waste of money studying it for 2 years (maybe like 10-15% of the language) and then stopping but however it isn't cheap to learn (£350).

I want to do well this time by achieving at least a 2:1 but I would definitely need to brush up hard before I start the course, as forgotten a lot of it and I would need to definitely put in a huge amount of effort. I am in my final year too which would make it even more challenging.

What do you guys think?
