I'm already so close to failing mathematics.
Why are you close to failing mathematics?
I've been doing mathematics for a while and I think I'm going to fail soon.
If you think you are failing then you should go to tutoring. Tutoring can be a good chance for someone to explain you the concepts better.
I have a confession: I hate tutorials. I would rather use the time for something more productive and I'm not a fan of talking.
Tutorials can be productive and you don't need to talk much. You should put effort into not failing the things you start.
