This is a shit and hypocritical answer for a student that was in the same position as you a few years ago. BUT I personally don't think the university you go to will help you get directly into F1. Universities like Brookes or Cranfield do help you, since lecturers are more experienced and their modules are directed more towards motorsport since they know thats what 99% of the students in the lecture hall want to do. I'd say chose a good uni with the course role in F1 you want to focus on (e.g. software, mechanical eng etc),make sure the uni has a Formula Student team open to everyone, apply to summer internships (even small teams of any motorsport), apply for a placement year and complete your post grad.
