will i do well in my further education? I was born October 20 1994

I am about to finish the course that I have been doing this year, so I have applied for another course. The course's that I have applied for are much more advanced than the one that I have just finished, as well as more difficult to receive a place in. I am unsure as to how well I will do in a new course and if i will be accepted into it, so I was wondering if there is any chance that I will do well??
