Just quickly glanced at this forum as I was in the same position as you guys last year, how time flies haha!
Noticed your post as it was one of the more recent ones
For life sciences, you don't get accepted to a specific degree, just to the school so basically you can chose to do any life science degree. I applied to do anatomy but I think I may change to Immunology or Pharmacology, can't decide. At Glasgow you don't need to decide your final degree to 2nd year (sometimes 3rd depending on what area).
In your first year you will do generalised biology courses, you won't do anything Neuroscience specific. You also have to either do Chemistry or Science Fundamentals if you haven't done chemistry before/not comfortable with it. Your 3rd subject can be whatever you like. I took Spanish beginners
I'm not sure how you enrol actually, can't remember, I think you may get an email and then that's when you go on and pick your classes and sort out your timetable, it's all done online.
Hopefully this helps, any questions just ask
