Im not sure how to continue my path to become a vet nurse

i am currently in year 11, im doing my gcses in around 10 months, my plan was to take A level biology in college, but i cant since you need a 6 in science and im doing foundation at my school, i can try to request to move up to higher so i can achieve a 6 ( i am getting the hghest marks in my class, i have gotten 55 multiple times), i found a college near me that offers animal themed courses. ( im not allowed to go to further colleges) the college is called central bedforshire college and im planning to do level 3 Animal managment, i have been looking at unis out of boredom and im scared im noy going to be able to go to any of them, and im very very confused on what most of the stuff even means since i've moved to the Uk a few years ago. i do not mind going out of the country for unis but i just want to know how high are my chance of actually becoming a vet nurse or even a vet?
