You might want to wait till next year in this case. From the FAQ's on the BA site:
I’m part way through a college/university course, can I apply?
This is your decision. Courses will start in the first few months of 2025 and if you are successful and are offered a place, you will not be able to defer to a future date. If you wish to finish your college/university course, you will need to apply to a future scheme.
